74HC5555D

Programmable delay timer with oscillator

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.

Features and benefits

  • 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

  • Very low power consumption in triggered start mode

  • 3 oscillator operating modes:

    • RC oscillator

    • Crystal oscillator

    • External oscillator

  • Device is unaffected by variations in temperature and VCC when using an external oscillator

  • Automatic power-ON reset

  • Schmitt trigger action on both trigger inputs

  • Direct drive for a power transistor

  • High precision due to digital timing

  • Complies with JEDEC standard no. 7 A

  • ESD protection:

    • HBM EIA/JESD22-A114A exceeds 2000 V

    • MM EIA/JESD22-A115-A exceeds 200 V

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

Applications

  • Motor control

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
