STMicroelectronics | ULN2065B

A Darlington Array is a semiconductor device which combines two or more bipolar transistors in a single device so that the current amplified by the first is amplified further by the second. This gives a high current gain , and takes less space than having multiple discrete transistors in the same configuration.

Designed to interface logic to a wide variety of high current, high voltage loads, these devices each contain four NPN darlington switches delivering up to 1.5 A with a specified minimum breakdown of 80 V and a sustaining voltage of 50 V. The ULN2065B, ULN2067B, ULN2069B and ULN2071B contain integral suppression diodes for inductive loads and have common emitters ; the ULN2075B and ULN2077B feature isolated darlington pinouts and are intended for applications such as emitter follower configurations. Inputs of the ULN2065B, ULN2069B and ULN2075B are compatible with popular 5 V logic families and the ULN2067B, ULN2071B and ULN2077B are compatible with 6-15 VCMOS and PMOS. The ULN2069B and ULN2071B include a predriver stage to provide extragain, reducing the load on control logic.

The ULN2065B is a 1.5A Darlington switch with an 80V minimum breakdown. It comes in a PDIP16 pkg.
