MC74VHCT125A
Quad Bus Buffer
with 3–State Control Inputs
fabricated with silicon gate CMOS technology. It achieves high speed
operation similar to equivalent Bipolar Schottky TTL while
maintaining CMOS low power dissipation.
set High to place the output into the high impedance state.
be used as a level converter for interfacing 3.3V to 5.0V, because it has
full 5V CMOS level output swings.
between 0V and 5.5V are applied, regardless of the supply voltage.
The output structures also provide protection when V CC = 0V. These
input and output structures help prevent device destruction caused by
supply voltage – input/output voltage mismatch, battery backup, hot
insertion, etc.
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7V, allowing the interface of 5V systems
to 3V systems.
