The ADT7461 is a ±1°C temperature monitor with series resistance cancellation, which can measure temperature in the range of 0°C to +127°C (default) or -55°C to +150°C.

The BUB323Z is a planar, monolithic, high-voltage power Darlington with a built-in active zener clamping circuit. This device is specifically designed for unclamped, inductive applications such as Electronic Ignition, Switching Regulators and Motor Control.

The MC34262/MC33262 are active power factor controllers specifically designed for use as a preconverter in electronic ballast and in off−line power converter applications. These integrated circuits feature an internal startup timer for stand−alone applications, a one quadrant multiplier for near unity power factor, zero current detector to ensure critical conduction operation, transconductance error amplifier, quickstart circuit for enhanced startup, trimmed internal bandgap reference, current sensing comparator, and a totem pole output ideally suited for driving a power MOSFET. Also included are protective features consisting of an overvoltage comparator to eliminate runaway output voltage due to load removal, input undervoltage lockout with hysteresis, cycle−by−cycle current limiting, multiplier output clamp that limits maximum peak switch current, an RS latch for single pulse metering, and a drive output high state clamp for MOSFET gate protection.

MC34064/D is a low voltage sensing circuit specifically designed for use as a reset controller in microprocessor-based systems. It offers the designer an economical solution for low voltage detection with a single external resistor. The MC34064 features a trimmed-in-package bandgap reference, and a comparator with precise thresholds and built-in hysteresis to prevent erratic reset operation. The open collector reset output is capable of sinking in excess of 10 mA, and operation is guaranteed down to 1.0 V input with low standby current. The MC devices are packaged in 3-pin TO-92, micro size TSOP-5, 8-pin SOIC-8 and Micro8 surface mount packages. The NCV device is packaged in SOIC-8 and TO-92. Applications include direct monitoring of the 5.0 V MPU/logic power supply used in appliance, automotive, consumer and industrial equipment.

The MC34161/MC33161 is a universal voltage monitor intended for use in a wide variety of voltage sensing applications. These devices offer the circuit designer an economical solution for positive and negative voltage detection. The circuit consists of two comparator channels each with hysteresis, a unique Mode Select Input for channel programming, a pinned out 2.54 V reference, and two open collector outputs capable of sinking in excess of 10mA. Each comparator channel can be configured as either inverting or noninverting by the Mode Select Input. This allows over, under, and window detection of positive and negative voltages. The minimum supply voltage needed for these devices to be fully functional is 2.0 V for positive voltage sensing and 4.0V for negative voltage sensing. Applications include direct monitoring of positive and negative voltages used in appliance, automotive, consumer, and industrial equipment.

The NCP2820 is a cost-effective mono Class-D audio power amplifier capable of delivering 2.65 W of continuous average power to 4.0 Ohm from a 5.0 V supply in a Bridge Tied Load (BTL) configuration. Under the same conditions, the output power stage can provide 1.4 W to a 8.0 Ohm BTL load with less than 1% THD+N. For cellular handsets or PDAs it offers space and cost savings because no output filter is required when using inductive tranducers. With more than 90% efficiency and very low shutdown current, it increases the lifetime of your battery and drastically lowers the junction temperature. The NCP2820 processes analog inputs with a pulse width modulation technique that lowers output noise and THD when compared to a conventional sigma-delta modulator. The device allows independent gain while summing signals from various audio sources. Thus, in cellular handsets, the earpiece, the loudspeaker and even the melody ringer can be driven with a single NCP2820. Due to its low 42dB A-weighted noise floor, a clean listening is guaranteed no matter the load sensitivity.

SA572 is a dual-channel, high-performance gain control circuit in which either channel may be used for dynamic range compression or expansion. Each channel has a full-wave rectifier to detect the average value of input signal, a linearized, temperature-compensated variable gain cell (�G) and a dynamic time constant buffer. The SA572 is intended for noise reduction in high-performance audio systems. It can also be used in a wide range of communication systems and video recording applications.

The MC74HC373A is an 8-bit 3-State Non-Inverting Transparent Latch with High-Performance Silicon-Gate CMOS.

The NTGS4111P is a power MOSFET produced by Semiconductor Components Industries, LLC. Its features include the use of a leading -30 V trench process with low RDS(on), a low profile package suitable for portable applications, a surface mount TSOP-6 package that saves board space, improved efficiency for battery applications, and a lead-free package that is available.

MC74HC244A Octal 3−State Noninverting Buffer/Line Driver/ Line Receiver

This datasheet provides detailed information on the MC14014B and MC14021B 8-bit static shift registers. These shift registers are primarily used for parallel-to-serial data conversion, synchronous and asynchronous parallel input, serial output data queuing, and other general purpose register applications requiring low power and/or high noise immunity.

The MC74HC573A is an octal 3-state noninverting transparent latch that utilizes high-performance silicon-gate CMOS technology. It has the same pinout as the LS573 and is compatible with standard CMOS outputs and LSTTL outputs with pullup resistors. The outputs change asynchronously when the latch enable is high, making the latch appear transparent to data. When the latch enable goes low, data meeting the setup and hold time is latched. The HC573A is functionally equivalent to the HC373A but has the data inputs on the opposite side of the package to facilitate PCB layout.

NCP3063, NCP3063B, NCV3063 1.5 A, Step-Up/Down/ Inverting Switching Regulators is a switching power chip produced by Onsemi. It is mainly used for step-down, step-up and inverting applications.
