MM74HC245A  
Octal 3-STATE Transceiver  
General Description  
Features  
The MM74HC245A 3-STATE bidirectional 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  
and high noise immunity usually associated with CMOS cir-  
cuitry, yet has speeds comparable to low power Schottky  
TTL circuits.  
Typical propagation delay: 13 ns  
Wide power supply range: 2–6V  
Low quiescent current: 80 A maximum (74 HC)  
3-STATE outputs for connection to bus oriented systems  
High output drive: 6 mA (minimum)  
Same as the 645  
This device has an active LOW enable input G and a direc-  
tion control input, DIR. When DIR is HIGH, data flows from  
the A inputs to the B outputs. When DIR is LOW, data flows  
from the B inputs to the A outputs. The MM74HC245A  
transfers true data from one bus to the other.  
This device can drive up to 15 LS-TTL Loads, and does not  
have Schmitt trigger inputs. All inputs are protected from  
damage due to static discharge by diodes to VCC and  
ground.
