The LP2987/8 are fixed-output 200 mA precision LDO voltage regulators with power-ON reset delay which can be implemented using a single external capacitor.
The LP2989 is a fixed-output 500 mA precision LDO regulator designed for use with ceramic output capacitors. It features ultra-low dropout voltage, low output noise, and low quiescent current.
The LP339 is a quad comparator with ultra-low power consumption, single-supply operation, ground-sensing, and is compatible with the CMOS logic family.
The LPC661 is a low power CMOS operational amplifier from National Semiconductor Corporation. It uses National Semiconductor Corporation's advanced Double-Poly Silicon-Gate CMOS process. This device has a wide supply voltage range (+5V to +15V), output swing up to the supply voltage range and can provide ground level output in the input common-mode range. The performance parameters of this device are better than most bipolar operational amplifiers, with a supply current of only 55μA.
The ADC0844 and ADC0848 are CMOS 8-bit successive approximation A/D converters with versatile analog input multiplexers. The 4-channel or 8-channel multiplexers can be software configured for single-ended, differential or pseudo-differential modes of operation. The differential mode provides low frequency input common mode rejection and allows offsetting the analog range of the converter. In addition, the A/D’s reference can be adjusted enabling the conversion of reduced analog ranges with 8-bit resolution. The A/Ds are designed to operate from the control bus of a wide variety of microprocessors. TRI-STATE output latches that directly drive the data bus permit the A/Ds to be configured as memory locations or I/O devices to the microprocessor with no interface logic necessary.
CD4051BM/CD4051BC is a single 8-channel analog multiplexer/demultiplexer, CD4052BM/CD4052BC is a dual 4-channel analog multiplexer/demultiplexer, CD4053BM/CD4053BC is a triple 2-channel analog multiplexer/demultiplexer. These analog multiplexers/demultiplexers have low 'ON' impedance and very low 'OFF' leakage currents, and can be controlled by digital signals.
54150 and 54151A are data selectors/multiplexers that can select the desired data source. 54150 can select 16 data sources, and 54151A can select 8 data sources. 54150 and 54151A both have a programmable input that must be at a low logic level to enable these devices.
The LM2832 is a monolithic, high frequency, PWM step-down DC/DC converter in a 6 Pin LLP and a 8 Pin eMSOP package. It provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area.
The NM27P040 is a 4096K Processor Oriented EPROM (POPTM) configured as 512K x 8. It is designed to simplify microprocessor interfacing while remaining compatible with standard EPROMs. It can reduce both wait states and glue logic when the specification improvements are taken advantage of in the system design. The NM27P040 is implemented in National’s advanced CMOS EPROM process to provide a reliable solution and access times as fast as 120 ns. The interface improvements address two areas to eliminate the need for additional devices to adapt the EPROM to the microprocessor and to eliminate wait states at the termination of the access cycle. Even with these improvements, the NM27P040 remains compatible with industry standard JEDEC pinout EPROMs. The time from CE or OE being negated until the outputs are guaranteed to be in the high impedance state has been reduced to eliminate the need for wait states at the termination of the memory cycle and the data-out hold time has been extended to eliminate the need to provide data hold time for the microprocessor by delaying control signals or latching and holding the data in external latches.
The LM3525 is a single-port USB power switch and over-current protection from TI. It is compatible with USB1.1 and USB2.0 standards, and has a 1ms fault flag delay, which can prevent erroneous over-current reporting caused by inrush currents during hot-plug events. The device is packaged in SO-8, and has a small size and low RON, making it an ideal choice for root hubs and ganged power control in space-critical self-powered hubs.
The LM320L/LM79LXXAC series is a 3-terminal negative voltage regulator with fixed output voltages and high output current capabilities. It has excellent transient response and stability, and comes with self-protection circuitry. Additionally, it can be combined with external circuitry to achieve boosted and/or adjustable voltages and currents.
The LM3501 is a fixed-frequency step-up DC/DC converter that is ideal for driving white LEDs for display backlighting and other lighting functions. With fully integrated synchronous switching (no external Schottky diode required) and a low feedback voltage (515 mV), power efficiency of the LM3501 circuit has been optimized for lighting applications in wireless phones and other portable products (single cell Li-Ion or 3-cell NiMH battery supplies). The LM3501 operates with a fixed 1 MHz switching frequency. When used with ceramic input and output capacitors, the LM3501 provides a small, low-noise, low-cost solution. Two LM3501 options are available with different output voltage capabilities. The LM3501-21 has a maximum output voltage of 21V and is typically suited for driving 4 or 5 white LEDs in series. The LM3501-16 has a maximum output voltage of 16V and is typically suited for driving 3 or 4 white LEDs in series (maximum number of series LEDs dependent on LED forward voltage). If the primary white LED network should be disconnected, the LM3501 uses internal protection circuitry on the output to prevent a destructive overvoltage event. A single external resistor is used to set the maximum LED current in LED-drive applications. The LED current can easily be adjusted by varying the analog control voltage on the control pin or by using a pulse width modulated (PWM) signal.
The 100331 is a low power triple D flip-flop with true and complement outputs, a Common Clock (CPC) and Master Set (MS) and Master Reset (MR) inputs. Each flip-flop has individual Clock (CPn), Direct Set (SDn) and Direct Clear (CDn) inputs. Data enters a master when both CPn and CPC are LOW and transfers to a slave when CPn or CPC (or both) go HIGH. The Master Set, Master Reset and individual CDn and SDn inputs override the Clock inputs. All inputs have 50 kΩ pull-down resistors.
