Pin configuration and function sub-micron silicon gate and double-layer metal are the same as those of the 74V1G04 but the 2 wiring C MOS technology. 74V1G14 has hysteresis. The internal circuit is composed of 3 stages This together with its schmitt trigger function including buffer output, which provide high noise allows it to be used on line receivers with slow immunity and stable output. rise/fall input signals. Power down protection is provided on input and 0 The input is equipped with protection circuits against static discharge, giving it ESD immunity to 7V can be accepted on input with no regard to the supply voltage. This device can be used to and transient excess voltage.
