Download the 74HC5555D datasheet PDF. This datasheet also covers the 74HC5555 variant, as both devices belong to the same programmable delay timer family and are provided as variant models within a single manufacturer datasheet.

General Description

The 74HC5555 is a precision programmable delay timer which consist of: 24-stage binary counter integrated oscillator (using external timing components) retriggerable/non-retriggerable monostable automatic power-ON reset output control logic

Key Features

  • Supply voltage range from 2.0 V to 6.0 V.
  • CMOS input levels.
  • 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.

74HC5555 Programmable delay timer with oscillator Rev. 4 — 5 July 2018 Product data sheet 1 General description The 74HC5555 is a precision programmable delay timer which consist of: • 24-stage binary counter • integrated oscillator (using external timing components) • retriggerable/non-retriggerable monostable • automatic power-ON reset • output control logic • oscillator control logic • overriding asynchronous master reset (MR). The 74HC5555 inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC. 2 Features and benefits • Supply voltage range from 2.0 V to 6.
