DESCRIPTION The 74VHC14 is an advanced high-speed CMOS HEX SCHMITT INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS 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
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 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.
