DESCRIPTION
The M74HC367 is an high speed CMOS HEX
BUS BUFFER 3-STATE OUTPUTS fabricated
with silicon gate C
2
MOS technology.
This device contains six buffers, four buffers are
controlled by an enable input (G1) and the other
two buffers are controlled by the other enable
input (G2); the outputs of each buffer group are
enabled when G1 and/or G2 inputs are held low,
and when held high, these outputs are disabled in
a high-impedance state.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
