74HC5555 - Programmable delay timer

Description

The 74HC/HCT5555 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).

They are specified in compliance with JEDEC standard no.

7A.

24-stage binary counter integra

Features

  • Positive and negative edge triggered.
  • Retriggerable or non-retriggerable.
  • Programmable delay minimum: 100 ns maximum: depends on input frequency and division ratio.
  • Divide-by range of 2 to 224.
  • Direct reset terminates output pulse.
  • Very low power consumption in triggered start mode.
  • 3 oscillator operating modes:.
  • RC oscillator.
  • Crystal oscillator.
  • External oscillator.
  • Device is unaffected by varia.
