ULN2070B
DESCRIPTION
Designed to interface logic to a wide variety of high current, high voltageloads, thesedeviceseach 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, ULN2068B and ULN2070B contain integral suppression diodes for inductive loads have mon emitters. The ULN2074B and ULN2076B feature isolated darlington pinouts and are intended for applications such as emitter followerconfigurations.Inputsof the ULN2064B, ULN2068B and ULN2074B are patible with popular 5 V logic families and the ULN2066B and ULN2076B are patible with 615 V CMOS and PMOS. Types ULN2068B and ULN2070Binclude a predriverstageto reduceloading on the control logic. PIN CONNECTIONS AND ORDER CODES
