IMPROVED LATCH-UP IMMUNITY

LOW NOISE: V

= 0.8V (MAX.)

regard to the supply voltage. This device can be

used to interface 5V to 3V.

OLP

Pin configuration and function are the same as

those of the 74VHC04 but the 74VHC14 has

hysteresis.

This together with its schmitt trigger function

allows it to be used on line receivers with slow

rise/fall input signals.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

DESCRIPTION

The 74VHC14 is an advanced high-speed CMOS

HEX SCHMITT INVERTER fabricated with

sub-micron silicon gate and double-layer metal

wiring C MOS technology.

The internal circuit is composed of 3 stages

including buffer output, which enables high noise

immunity and stable output.

Power down protection is provided on all inputs

and 0 to 7V can be accepted on inputs with no
