DESCRIPTION

· The 74HC5555 is a precision programmable delay timer with an integrated oscillator, 24-stage binary counter, and various control logics.

· It features automatic power-ON reset, overriding asynchronous master reset, and input clamp diodes for voltage interfacing.

FEATURES

· Operates with a supply voltage range from 2.0 V to 6.0 V.

· Supports CMOS input levels and is triggered by both positive and negative edges.

· Offers retriggerable or non-retriggerable modes with programmable delays from 100 ns upwards.

· Includes three oscillator operating modes: RC, crystal, and external oscillator.

· Features low power consumption, Schmitt trigger action on trigger inputs, and high precision digital timing.

· Provides ESD protection exceeding 2000 V (HBM) and 200 V (MM).

APPLICATIONS

· Suitable for applications requiring precise timing and delay generation.

· Ideal for use in environments with varying temperatures and supply voltages when using an external oscillator.

· Can be used in systems that require direct drive for power transistors and robust ESD protection.
