The TC74VHC367 and 368 are advanced high speed CMOS

HEX BUS BUFFERs fabricated with silicon gate CMOS

technology.

They achieve the high speed operation similar to equivalent.

Bipolar Schottky TTL while maintaining the CMOS low

power dissipation.

They contain six buffers; four buffers are controlled by an

enable input (G1), and the other two buffers are controlled by

another enable input (G2). The outputs of each buffer group

are enabled when G1 and/or G2 inputs are held low; if held

high, these outputs are in a high impedance state.

The TC74VHC367 is a non-inverting output type, while the

TC74VHC368 is an inverting output typc.

An input protection circuit ensures that 0 to 7V can be

applied to the input pins without regard to the supply

voltage. This device can be used to interface 5V to 3V

systems and two supply systems such as battery back up.

This circuit prevents device destruction due to mismatched

supply and input voltages.
