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
Delay circuits
Precision timing
Domestic appliances

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.
