ULN2075B Description

Short technical summary and product information.

The ULN2075B from TE Connectivity is a quad Darlington switch IC designed to interface logic signals with high current, high voltage loads. Each of the four NPN Darlington switches can deliver up to 1.75A of continuous collector current with a minimum breakdown voltage of 80V.

 

This device features an isolated Darlington pinout, making it suitable for applications such as emitter follower configurations. The input voltage compatibility spans popular logic families, with specific versions designed for 5V logic and others for 6-15V CMOS and PMOS. The ULN2075B operates within an ambient temperature range of -20°C to +85°C and is housed in a PowerDIP package.

 

Key electrical characteristics include a collector-emitter sustaining voltage of at least 50V and a maximum power dissipation of 1W at 70°C ambient temperature. The device is designed for reliable performance in demanding applications requiring robust switching capabilities.
