General Description  
Features  
Y
Typical propagation delay: 14 ns  
These TRI-STATE buffers utilize advanced silicon-gate  
CMOS technology and are general purpose high speed non-  
inverting buffers. They possess high drive current outputs  
which enable high speed operation even when driving large  
bus capacitances. These circuits achieve speeds compara-  
ble to low power Schottky devices, while retaining the ad-  
vantage of CMOS circuitry, i.e., high noise immunity, and  
low power consumption. All three devices have a fanout of  
15 LS-TTL equivalent inputs.

The MM74HCA244 is a non-inverting buffer and has two  
active low enables (1G and 2G). Each enable independently  
controls 4 buffers. This device does not have Schmitt trigger  
inputs.  
All inputs are protected from damage due to static dis-  
and ground.
