ULN2066B Datasheet | STMicroelectronics

Features - Output current to 1.5 A for each Darlington - Minimum breakdown 50 V - Sustaining voltage at least 35 V - Integral suppression diodes (ULN2064B, ULN2066B and ULN2068B - Isolated Darlington pinout (ULN2074B) - Versions patible with all popular logic families Description 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 50 V and a sustaining voltage of 35 V measured at 100 m A. The ULN2064B, ULN2066B and ULN2068B contain integral suppression diodes for inductive loads have mon emitters. The ULN2074B feature isolated Darlington pinouts and is intended for Power DIP-16 applications such as emitter follower configurations. Inputs of the ULN2064B, ULN2068B and ULN2074B are patible with popular 5 V logic families and the ULN2066B are patible with 6 - 15 V CMOS and PMOS. Type ULN2068B includes a pre-driver stage to reduce loading on the control logic. Table 1.
