General Description
The MM74HCT245 3-STATE bi-directional buffer utilizes
advanced silicon-gate CMOS technology and is intended
for two-way asynchronous communication between data
buses. It has high drive current outputs which enable high
speed operation even when driving large bus capaci-
tances. This circuit possesses the low power consumption
of CMOS circuitry, yet has speeds comparable to low
power Schottky TTL circuits.
This device is TTL input compatible and can drive up to 15
LS-TTL loads, and all inputs are protected from damage
due to static discharge by diodes to V
The MM74HCT245 has one active low enable input (G),
and a direction control (DIR). When the DIR input is HIGH,
data flows from the A inputs to the B outputs. When DIR is
LOW, data flows from B to A.
MM74HCT devices are intended to interface between TTL
and NMOS components and standard CMOS devices.
These parts are also plug-in replacements for LS-TTL
devices and can be used to reduce power consumption in
existing designs.
