74HC5555D End of life

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.

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.
