Quad 2-Input NAND Schmitt
Trigger
The MC74VHCT132A is an advanced high speed CMOS Schmitt NAND
trigger fabricated with silicon gate CMOS technology. It achieves high speed
operation similar to equivalent Bipolar Schottky TTL while maintaining
CMOS low power dissipation.
Pin configuration and function are the same as the MC74VHC00, but the
inputs have hysteresis and, with its Schmitt trigger function, the VHCT132A
can be used as a line receiver which will receive slow input signals.
The VHCT inputs are compatible with TTL levels. This device can be used
as a level converter for interfacing 3.3V to 5.0V, because it has full 5V CMOS
level output swings.
The VHCT132A input structures provide protection when voltages
between 0V and 5.5V are applied, regardless of the supply voltage. The
output structures also provide protection when VCC = 0V. These input and
output structures help prevent device destruction caused by supply voltage
– input/output voltage mismatch, battery backup, hot insertion, etc.
The internal circuit is composed of three stages, including a buffer 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.
