ORDER CODE: 74V1T14S 74V1T14C interface 5V to 3V. Pin configuration an d function are the same as those of t he V1G04 but the V1G14 has hysteresis. The schmitt trigger f unction 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 t echnology. 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. This device can be used t o
