ULN2003APWRG4 Description

Short technical summary and product information.

The ULN2003APWRG4 from Texas Instruments is a high-voltage, high-current Darlington transistor array. It comprises seven NPN Darlington pairs, each capable of handling a collector current of 500mA and featuring high-voltage outputs up to 50V. Common-cathode clamp diodes are integrated for switching inductive loads.

 

This device offers an output current of 500mA per channel and a peak output current of 0.5A. The input compatibility includes CMOS and TTL logic levels, with a typical delay time of 250ns. The operating temperature range is from -40°C to 70°C.

 

The ULN2003APWRG4 is supplied in a 16-TSSOP surface-mount package, measuring 16-TSSOP (0.173", 4.40mm Width). Its design makes it suitable for applications such as relay drivers, hammer drivers, lamp drivers, and display drivers.

 

Key electrical characteristics include 7 drivers per package, a 50V maximum switching voltage, and 500mA maximum output current per channel. The input interface is parallel and inverting, with an output configuration for low-side switching.
