TC74VHC9151P, TC74VHC9151FK TC74VHC9152P, TC74VHC9152FK TC74VHC9151P/FK 9-Bit Schmitt Buffer TC74VHC9152P/FK 9-Bit Schmitt Inverter
The TC74VHC9151/9152 are an ultra-high-speed 9-bit Schmitt Buffer / Inverter fabricated using silicon-gate CMOS technology. The TC74VHC9151/9152 combines low power consumption of CMOS with Schottky TTL speeds. TC74VHC9151 output is a non-inverting type and the TC74VHC9152 output is an inverting type. All the inputs have hysteresis between the positive-going and negative-going thresholds. Thus the TC74VHC9151/9152 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 VCC. This 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 TC74VHC9151/9152 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.
