MC74VHCT244A
Octal Bus Buffer/Line Driver
with 3State Outputs
The MC74VHCT244A is an advanced high speed CMOS octal bus
buffer fabricated with silicon gate CMOS technology. It achieves high
speed operation similar to equivalent Bipolar Schottky TTL while
maintaining CMOS low power dissipation.
The MC74VHCT244A is a noninverting 3state buffer, and has two
activelow output enables. This device is designed to be used with
3state memory address drivers, etc.
The VHCT inputs are compatible with TTL levels. This device can
be used as a level converter for interfacing 3.3 V to 5.0 V, because it
has full 5.0 V CMOS level output swings.
The VHCT244A input and output (when disabled) structures
provide protection when voltages between 0 V and 5.5 V are applied,
regardless of the supply voltage. These input and output structures
hel p prevent devi c e des t r uct i o n caus e d by suppl y
voltageinput/output voltage mismatch, battery backup, hot insertion,
etc.
