SA555 Description

Short technical summary and product information.

The Texas Instruments SA555 is a versatile precision timing circuit capable of producing accurate time delays or oscillations. It supports both astable and monostable operating modes, allowing for flexible timing from microseconds to hours. The duty cycle is adjustable in astable mode, and the output is TTL-compatible, capable of sinking or sourcing up to 200mA.

 

This timer IC operates over a wide supply voltage range of 5V to 15V and has a typical quiescent current of 2mA. The operating temperature range is -40°C to 85°C. The SA555 is available in SOIC and PDIP packages.

 

It is suitable for a wide range of applications requiring precise timing control, such as pulse generation, waveform generation, and time-delay circuits. The internal trigger and threshold levels, approximately one-third and two-thirds of the supply voltage respectively, can be adjusted via the control voltage pin.
