SA555D Description

Short technical summary and product information.

The SA555D is a precision timing circuit IC manufactured by STMicroelectronics, capable of producing accurate time delays or oscillations. It can function in astable or monostable modes, with adjustable duty cycle. The device operates within a voltage range of 4.5V to 16V and supports a frequency up to 500kHz.

 

This timer IC is housed in an 8-SOIC package and is designed for surface mount applications. The operating temperature range is specified as -40°C to 85°C. The SA555D features a TTL-compatible output that can sink or source up to 200mA. It is noted as an obsolete part by the manufacturer.

 

In monostable mode, the timed interval is controlled by an external resistor and capacitor network. In astable mode, the frequency and duty cycle are independently controlled by two external resistors and a capacitor. The trigger and threshold levels are approximately one-third and two-thirds of the supply voltage, respectively, and can be adjusted via the control voltage pin.
