Functional Description
• Quad 2-Input OR Gate

General
The 74VHCT32AFT 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
