MM74HC244  
Octal 3-STATE Buffer  
General Description  
The MM74HC244 is a non-inverting buffer and has two  
Features  
Typical propagation delay: 14 ns  
active low enables (1G and 2G); each enable indepen-  
3-STATE outputs for connection to system buses  
Wide power supply range: 2–6V  
dently controls  
4 buffers. This device does not have  
Schmitt trigger inputs.  
Low quiescent supply current: 80  
Output current: 6 mA  
A
These 3-STATE buffers utilize advanced silicon-gate  
CMOS technology and are general purpose high speed  
non-inverting buffers. They possess high drive current out-  
puts which enable high speed operation even when driving  
large bus capacitances. These circuits achieve speeds  
comparable to low power Schottky devices, while retaining  
the advantage of CMOS circuitry, i.e., high noise immunity,  
and low power consumption. All three devices have a  
fanout of 15 LS-TTL equivalent inputs.  
All inputs are protected from damage due to static dis-  
charge by diodes to VCC and ground.
