74AHCT14A

Hex inverting Schmitt trigger

The 74AHCT14A is a hex inverter with Schmitt-trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.

Designed to operate over a VCC range from 4.5 V to 5.5 V, the inputs are TTL compatible. This range allows the device to be used to translate from 3.3 V to 5 V.

This device is fully specified for partial Power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

特性

  • Direct interface with TTL levels

  • Supply voltage range from 4.5 V to 5.5 V

  • Typical tpd of 3.7 ns at 5 V

  • Typical VOL(p)< 0.8 V at VCC = 5 V, Tamb = 25 °C

  • Typical VOH(v)> 2.3 V at VCC = 5 V, Tamb = 25 °C

  • Supports mixed-mode voltage operation on all ports

  • IOFF circuitry provides partial Power-down mode operation

  • Latch-up performance exceeds 250 mA per JESD 78 Class II

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 3000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 2000 V

  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
