The TC74VHCT32A is an advanced high speed CMOS 2-INPUT OR

GATE fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent Bipolar Schottky

TTL while maintaining the CMOS low power dissipation.

The internal circuit is composed of 4 stages including buffer output, which

provide high noise immunity and stable output.

The input voltage are compatible with TTL output voltage.

This device 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.

Note: VCC = 0 V
