MM74HC244
Octal 3-STATE Buffer
General Description
The MM74HC244 is a non-inverting buffer and has two
active low enables (1G and 2G); each enable indepen-
dently controls 4 buffers. This device does not have
Schmitt trigger inputs.
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 V
CC
and ground.
