Functional Description

• Hex Schmitt Inverter

General

The 74VHCV14FT is an advanced high speed CMOS SCHMITT INVERTER fabricated with silicon gate CMOS

technology.

It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS

low power dissipation.

Input pin have hysteresis between the positive-going and negative-going thresholds. Thus the 74VHCV14FT is

capable of squaring up transitions of slowly changing input signals such as line receivers.

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, etc.

Note: VCC = 0 V
