General Description  
These TRI-STATE bidirectional inverting and non-inverting  
buffers utilize advanced silicon-gate CMOS technology and  
are intended for two-way asynchronous communication be-  
tween data buses. They have high drive current outputs  
which enable high speed operation when driving large bus  
capacitances. These circuits possess the low power dissi-  
pation and high noise immunity associated with CMOS cir-  
cuits, but speeds comparable to low power Schottky TTL  
circuits. They can also drive 15 LS-TTL loads.  
GAB enables the B outputs. This device does not have  
Schmitt trigger inputs.  
All inputs are protected from damage due to static dis-  
and ground.

High output current: 6 mA (74HC)  
Wide power supply range: 26V  
Low quiescent supply current: 80 mA (74HC)  
The MM54HC243/MM74HC243 is a non-inverting buffer  
and the MM54HC242/MM74HC242 is an inverting buffer.  
Each device has one active high enable (GBA), and one  
active low enable (GAB). GBA enables the A outputs and
