The 74VHC540FT/74VHC541FT are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon
gate C2MOS technology.
They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS
low power dissipation.
The 74VHC540FT is an inverting type, and the 74VHC541FT is a non-inverting type.
When either G1 or G2 are high, the terminal outputs are in the high-impedance state.
An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply
voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up.
This circuit prevents device destruction due to mismatched supply and input voltages
