They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
The TC74VHCT540A is an inverting type and, the TC74VHCT541A is a non-inverting type.
When either G1 or G2 are high, the terminal outputs are in the high-impedance state.
The input voltage are patible with TTL output voltage. These devices may be used as a level converter for interfacing 3.3 V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc.
