74VHC14

Hex Schmitt Inverter

General Description

The VHC14 is an advanced high speed CMOS Hex

Schmitt Inverter fabricated with silicon gate CMOS technol

ogy. It achieves the high speed operation similar to equiva-

lent Bipolar Schottky TTL while maintaining the CMOS low

power dissipation. Pin configuration and function are the

same as the VHC04 but the inputs have hysteresis

between the positive-going and negative-going input

thresholds, which are capable of transforming slowly

changing input signals into sharply defined, jitter-free out

put signals, thus providing greater noise margin than con-

ventional inverters.

An input protection circuit ensures that 0V to 7V can be

applied to the input pins without regard to the supply volt

age. This device can be used to interface 5V to 3V systems

and two supply systems such as battery back up. This cir

cuit prevents device destruction due to mismatched supply

and input voltages.
