MM54HC365/MM74HC365 Hex TRI-STATEÉ Buffer
MM54HC366/MM74HC366 Inverting Hex TRI-STATE Buffer
MM54HC367/MM74HC367 Hex TRI-STATE Buffer
MM54HC368/MM74HC368 Inverting Hex TRI-STATE Buffer
General Description
These TRI-STATE buffers are general purpose high speed
inverting and non-inverting buffers that utilize advanced silicon-
gate CMOS technology. They have high drive current
outputs which enable high speed operation even when driving
large bus capacitances. These circuits possess the low
power dissipation of CMOS circuitry, yet have speeds comparable
to low power Schottky TTL circuits. All 4 circuits are
capable of driving up to 15 low power Schottky inputs.
The MM54/74HC366 and the MM54/74HC368 are inverting
buffers, where as the MM54/74HC365 and the MM54/
74HC367 are non-inverting buffers. The MM54/74HC365
and the MM54/74HC366 have two TRI-STATE control inputs
(G1 and G2) which are NORed together to control all
six gates. The MM54/74HC367 and the MM54/74HC368
also have two output enables, but one enable (G1) controls
4 gates and the other (G2) controls the remaining 2 gates.
All inputs are protected from damage due to static discharge
by diodes to VCC and ground.
