74V1T14 SINGLE SCHMITT INVERTER ■ ■ ■ ■ ■ ■ ■ ■ HIGH SPEED: tPD = 4.7 ns (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 1 µA (MAX.) at TA = 25 oC TYPICAL HYSTERESIS: Vh =0.7V AT VCC =4.5V POWER DOWN PROTECTION ON INPUT SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 4.5V to 5.5V IMPROVED LATCH-UP IMMUNITY 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. This device can be used to S (SOT23-5L) C (SC-70) ORDER CODE: 74V1T14S 74V1T14C interface 5V to 3V. 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.
