Pin configuration and function SINGLE SCHMITT INVERTER fabricated with are the same as those of the 74V1T04 but the sub-micron silicon gate and double-layer metal 74V1T14 has hysteresis. 2 wiring C MOS technology. This together with its schmitt trigger function The internal circuit is composed of 3 stages allows it to be used on line receivers with slow including buffer output, which provide high noise rise/fall input signals. immunity and stable output. The input is equipped with protection circuits against static discharge, giving it ESD immunity Power down protection is provided on input and 0 to 7V can be accepted on input with no regard to and transient excess voltage. the supply voltage.
