DESCRIPTION
The M74HCT367 is an high speed CMOS HEX BUS BUFFER 3-STATE OUTPUTS fabricated with silicon gate C2MOS 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,
