TC74VHC9125P/FT/FK 5-bit Universal Schmitt Buffer with 3-State Outputs

TC74VHC9126P/FT/FK 5-bit Universal Schmitt Buffer with 3-State Outputs

The TC74VHC9125/9126 are an ultra-high-speed 5-bit Schmitt

buffer fabricated using silicon-gate CMOS technology. The

TC74VHC9125/9126 combines low power consumption of CMOS

with Schottky TTL speeds.

Y1 to Y4 outputs can be put in the high-impedance state by

determines the logical inversion of data.A logic LOW on the

CONT input configures the TC74VHC9125/9126 as an inverter; a

logic

HIGH

on

the

CONT

input

configures

the

TC74VHC9125/9126 as a buffer.

TC74VHC9125 Y5 output is an inverting type, and the

TC74VHC9126 Y5 output is a non-inverting type.

All the inputs have hysteresis between the positive-going and

negative-going thresholds. Thus the TC74VHC9125/9126 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

to be tolerant of up to 5 volts even when power supply is down.

The input power-down protection capability makes the

TC74VHC9125/9126 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.

Features

• All inputs are provided with power-down protection.
