Pin configuration and function are the same as those of the V1G04 but the V1G14 has hysteresis. The schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals. DESCRIPTION The 74V1T14 is an advanced high-speed CMOS SINGLE 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 provide high noise immunity and stable output. Power down protection is provided on input and 0 to 7V can be accepted on input with no regard to the supply voltage.
