General Description  
The MM74HC245A 3STATE bidirectional buffer utilizes  
advanced silicongate CMOS technology, and is intended for  
twoway asynchronous communication between data buses. It has  
high drive current outputs which enable high speed operation even  
when driving large bus capacitances. This circuit possesses the low  
power consumption and high noise immunity usually associated with  
CMOS circuitry, yet has speeds comparable to low power Schottky  
TTL circuits.  
This device has an active LOW enable input G and a direction  
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.
