74AHCT07A - Hex buffer

Description

The 74AHCT07A is a hex buffer with open-drain outputs.

The outputs are open-drain and can be connected to other open-drain outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions.

Features

  • Direct interface with TTL levels.
  • Supply voltage range from 4.5 V to 5.5 V.
  • Typical tPZL of 3.4 ns at 5 V.
  • Typical VOL(p) < 0.8 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 3 kV.
  • MM JESD22-A115-A exceeds 150 V.
  • CDM JESD22-C101E ex.

74AHCT07A Hex buffer with open-drain outputs Rev. 1 — 19 December 2016 Product data sheet 1. General description The 74AHCT07A is a hex buffer with open-drain outputs. The outputs are open-drain and can be connected to other open-drain outputs to implement active-LOW wired-OR or active-HIGH wired-AND functions. Designed to operate over a VCC range from 4.5 V to 5.5 V, the inputs are TTL compatible, which allows the device to be used to translate from 3.3 V to 5 V. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. 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. 2.
