national semiconductor 54F/74F191 Up/Down Binary Counter with Preset Ripple Clock Manual
The ’F191 is a reversible modulo-16 binary counter featuring synchronous counting and asynchronous presetting. The preset feature allows the ’F191 to be used in programmable dividers. The Count Enable input, the Terminal Count output and Ripple Clock output make possible a variety of methods of implementing multistage counters. In the counting modes, state changes are initiated by the rising edge of the clock. The counter has a high-speed, 125 MHz typical count frequency, supports synchronous counting, asynchronous parallel load and cascading.
National Semiconductor DS16149/DS36149 DS16179/DS36179 Hex MOS Drivers handbook
The DS16149-DS36149 and DS16179-DS36179 are Hex MOS drivers with outputs designed to drive large capacitive loads up to 500 pF associated with MOS memory systems. PNP input transistors are employed to reduce input currents allowing the large fan-out to these drivers needed in memory systems. The circuit has Schottky-clamped transistor logic for minimum propagation delay and a disable control that places the outputs in the logic ‘‘1’’ state. This is especially useful in MOS RAM applications where a set of address lines has to be in the logic ‘’1’’ state during refresh. The DS16149-DS36149 has a 15 X resistor in series with the outputs to dampen transients caused by the fast-switching output. The DS16179-DS36179 has a direct low impedance output for use with or without an external resistor.

NATIONAL LMV232 DATA SHEET
The LMV232 dual RF detector is designed for RF transmit power measurement in mobile phones. This dual mean square IC is especially suited for accurate power measurement of RF signals exhibiting high peak-to-average ratios used in 3G and UMTS/CDMA applications. The LMV232 saves calibration steps and system certification and is highly accurate. The circuit operates with a single supply from 2.5 to 3.3V. The LMV232 contains a mean square detector with two sequentially selectable RF inputs. The RF input power range of the device has been optimized for use with a 20 dB directional coupler, without the need for additional external components. A single external RC combination between FB and OUT provides an externally configurable gain and LF filter bandwidth of the device. The device has two digital interfaces. A shutdown function is available to set the device in a low-power shutdown mode. In case SD = HIGH, the device is in shutdown, if SD = LOW the device is active. The Band-Select function controls the selection of the active RF input channel. In case BS = HIGH, RFIN1 is active. In case BS = LOW, RFIN2 is active. The dual mean square detector is offered in an 8-bump micro SMD 1.5 x 1.5 x 0.6 mm package. This micro SMD package has the smallest footprint and height.
national semiconductor LM6211 Low Noise RRO Op-Amp with CMOS Input 24V Operation handbook
LM6211 is a wide bandwidth, low noise op amp with a wide supply voltage range and a low input bias current. The device operates with a single supply voltage of 5V to 24V, is unity gain stable, has a ground-sensing CMOS input stage, and offers rail-to-rail output swing. The LM6211 is designed to provide optimal performance in high voltage, low noise systems. The device has a unity gain bandwidth of 20 MHz and an input referred voltage noise density of 5.5 nV/A, frequency 10 kHz. LM6211 achieves these specifications with a low supply current of only 1 mA. LM6211 has a low input bias current of 2.3 pA, an output short circuit current of 25 mA and a slew rate of 5.6 V/μs. LM6211 also features a low common-mode input capacitance of 5.5 pF which makes it ideal for use in wide bandwidth and high gain circuits. LM6211 is well suited for low noise applications that require an op amp with very low input bias currents and a large output voltage swing, like active loop-filters for wide-band PLLs. A low total harmonic distortion, 0.01% at 1 kHz with loads as high as 600 Ω, also makes the LM6211 ideal for high fidelity audio and microphone amplifiers. The LM6211 is available in the small SOT package, allowing the user to implement ultra-small and cost effective board layouts.
