Description

The 74VHC14 device is an advanced high-speed

CMOS hex Schmitt inverter manufactured with

sub-micron silicon gate and double-layer metal

wiring C2MOS technology. The internal circuit is

composed of 3 stages including a buffer output,

which provides high noise immunity and stable

output.

Power-down protection is provided on all inputs

and 0 to 7 V can be accepted on inputs

regardless of the supply voltage. This device can

be used to interface from 5 V to 3 V.

Pin configuration and function are the same as

those of the 74VHC04 device but the 74VHC14

device has hysteresis.

This along with its Schmitt trigger function allows

the device 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 2 kV ESD immunity and transient excess

voltage.
