Description

The 74VHCT14A is an advanced high-speed CMOS HEX SCHMITT INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOStechnology.

The internal circuit is composed of 3 stages including buffer output, which enable high noise immunity and stable output.

Power down protection of the 74VHCT14A is provided on all inputs and outputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. Pin configuration and function are the same as those of the VHC04 but the VHC14 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 of the 74VHCT14A are equipped withprotection circuits against static discharge, giving them 2KV ESD immunity and transient excessvoltage.
