74HC5555D
Description
The 74HC5555 is a precision programmable delay timer which consist of: • 24-stage binary counter • integrated oscillator (using external timing ponents) • retriggerable/non-retriggerable monostable • automatic power-ON reset • output control logic • oscillator control logic • overriding asynchronous master reset (MR).
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
- 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
Applications
- Motor control
