NA556DR Description

Short technical summary and product information.

The Texas Instruments NA556DR is a dual precision timer integrated circuit, functioning as a general-purpose timer. It is designed to operate in astable or monostable modes using external resistor-capacitor timing control. Each timer within the package provides independent timing circuits.

 

Key electrical characteristics include a supply voltage range of 4.5V to 16V and a quiescent current of typically 4 mA. The output can sink or source up to 200 mA and is TTL-compatible. The operating temperature range is -40°C to 105°C.

 

This component is housed in a 14-SOIC package, suitable for surface mount applications. The package dimensions are 14-SOIC (0.154", 3.90mm Width). The NA556DR is designed for reliable performance in various timing and oscillation circuits.

 

Compliance information indicates RoHS3 compliance, MSL 1 Unlimited, and REACH Unaffected status. However, these compliance details are unverified and should be reviewed.
