SA556N Description

Short technical summary and product information.

The SA556N from Texas Instruments is a dual timer integrated circuit, offering two independent timing circuits within a single package. This device is based on the 555 timer architecture and is suitable for astable or monostable operation using external resistor-capacitor timing control.

 

Key electrical specifications include an operating voltage range of 4.5V to 16V and a typical current consumption of 20 mA. The timer can achieve frequencies up to 100kHz. The operating temperature range is specified from -40°C to 85°C, making it suitable for extended temperature applications.

 

This component is housed in a 14-PDIP package, designed for through-hole mounting. The package dimensions are 14-DIP (0.300", 7.62mm). The TTL-compatible output can sink or source up to 200mA. Unused inputs should be tied to an appropriate logic level to prevent false triggering.

 

The SA556N is a versatile component for various timing and oscillation tasks in electronic designs.
