SE555P Description

Short technical summary and product information.

The Texas Instruments SE555P is a versatile general-purpose timer IC designed for precision timing applications. It can function in both astable and monostable modes, allowing for flexible timing from microseconds to hours.

 

Key electrical specifications include an operating voltage range of 4.5V to 18V, with a typical quiescent current of 2mA and a maximum of 10mA. The device supports a frequency output of up to 100kHz and its output circuit can sink or source up to 200mA. The operating temperature range is specified from -55°C to 125°C, making it suitable for demanding environments.

 

This timer IC is available in an 8-PDIP through-hole package, with an alternative 8-DIP (0.300", 7.62mm) package also noted. The SE555P is designed with TTL-compatible outputs and features adjustable duty cycle capabilities. Unused inputs should be tied to an appropriate logic level to prevent false triggering.
