74HC5555D Overview
Key Specifications
Package: SOP
Mount Type: Surface Mount
Pins: 16
Operating Voltage: 5 V
Description
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.
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: – 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
