GeneralGeneralGeneralGeneral The 74VHC9151FT/74VHC9152FT are an ultra-high-speed 9-bit Schmitt Buffer / Inverter fabricated using silicon-gate CMOS technology. The 74VHC9151FT/74VHC9152FT combines low power consumption of CMOS with Schottky TTL speeds. 74VHC9151FT output is a non-inverting type and the 74VHC9152FT output is an inverting type. All the inputs have hysteresis between the positive-going and negative-going thresholds. Thus the 74VHC9151FT/74VHC9152FT are capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. Additionally, all the inputs have a newly developed protection circuit without a diode returned to V . This CC enables the inputs to be tolerant of up to 5 volts even when power supply is down. The input power-down protection capability makes the 74VHC9151FT/74VHC9152FT ideal for a wide range of applications, such as interfacing between different voltages, voltage translation from 5 V to 3 V and battery back- up circuits. 3. 3.
