MM74HCT245  
Octal 3-STATE Transceiver  
data flows from the A inputs to the B outputs. When DIR is  
LOW, data flows from B to A.  
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.  
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.  
Features  
■ TTL input compatible  
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 VCC and ground.  
■ 3-STATE outputs for connection to system busses  
■ High output drive current: 6 mA (min)  
■ High speed: 16 ns typical propagation delay  
■ Low power: 80 µA (74HCT Series)  
The MM74HCT245 has one active low enable input (G),  
and a direction control (DIR). When the DIR input is HIGH,
