74AHCT14A

Hex inverting Schmitt trigger

The 74AHCT14A is a hexadecimal 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.

Features and benefits

  • 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:
