Mini-SPM is a Smart Power Module that consists of high performance MOSFET, which can be used for high frequency PWM inverter application.

This document introduces a system approach for designing high performance bootstrap gate driver circuits for power MOSFETs and IGBTs, in high-frequency, high-power, and high efficiency switch applications. Different experience electrical engineers can benefit from it.

This document describes the features and characteristics of the KA331 V-F converter from Fairchild Semiconductor Corporation, including guaranteed linearity, low power dissipation, wide range of full-scale frequency, and compatibility with all logic forms. The converter provides an output pulse train at a frequency precisely proportional to the applied input voltage and is suitable for various applications such as analog-to-digital conversion, frequency-to-voltage conversion, and linear frequency modulation or demodulation.

The NC7WZ240 is a Dual Inverting Buffer with independent active LOW enables for the 3-STATE outputs. The Ultra High Speed device is fabricated with advanced CMOS technology to achieve superior switching performance with high output drive while maintaining low static power dissipation over a broad VCC operating range. The device is specified to operate over the 1.65V to 5.5V VCC operating range.

This application note compares Fairchild Semiconductor's logic solutions for buffered (or registered) DIMMs to other competitive solutions. Proper selection of the logic devices to register and redrive heavily loaded address and control signal paths requires careful consideration of device parameters and can result in a SDRAM DIMM design that uses the fewest components and provides reliable circuit performance.

The VHC273 is an advanced high speed CMOS Octal D-type flip-flop fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

The 74VHC221A is an advanced high-speed CMOS Monostable Multivibrator fabricated with silicon gate CMOS technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. Each multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit input. Also included is a clear input that, when taken LOW, resets the one-shot. The VHC221A can be triggered on the positive transition of the clear while A is held LOW and B is held HIGH. The VHC221A is non-retriggerable and therefore cannot be retriggered until the output pulse times out. The output pulse width is determined by the equation: PW = (Rx)(Cx), where PW is in seconds, R is in ohms, and C is in farads.

This application note discusses the input and output characteristics of the MM74HC high-speed CMOS logic family, as well as how these characteristics are affected by various parameters such as power supply voltage and temperature. Also, for those users who have been designing with metal-gate CMOS and TTL logic, this application note compares the notable differences and features of high-speed CMOS to those logic families.

The 74VHC393 is a dual 4-bit binary counter with features such as high speed, low power dissipation, and high noise immunity. It is fabricated with silicon gate CMOS technology and can achieve 8-bit binary counting or frequency division. The device changes state on the negative going transition of the CLOCK pulse and can be reset to '0' by a HIGH at the CLEAR input. It is suitable for interfacing 5V to 3V systems and two supply systems such as battery backup.

74VHC175 is an advanced high-speed CMOS device fabricated with silicon gate CMOS technology. It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.

The NC7SZ19 is a 1-of-2 decoder with a common output enable. The device is fabricated with advanced CMOS technology to achieve ultra-high speed with high output drive while maintaining low static power dissipation over a broad VCC operating range.
