ULN2064B, ULN2066B ULN2068B, ULN2074B 50 V - 1.5 A quad Darlington switches 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) PowerDIP-16 Versions compatible with all popular logic families Description Designed to interface logic to a wide variety of applications such as emitter follower high current, high voltage loads, these devices configurations. Inputs of the ULN2064B, each contain four NPN Darlington switches ULN2068B and ULN2074B are compatible with delivering up to 1.5 A with a specified minimum popular 5 V logic families and the ULN2066B are breakdown of 50 V and a sustaining voltage of 35 compatible with 6 - 15 V CMOS and PMOS. Type V measured at 100 mA. The ULN2064B, ULN2068B includes a pre-driver stage to reduce ULN2066B and ULN2068B contain integral loading on the control logic. suppression diodes for inductive loads have common emitters. The ULN2074B feature isolated Darlington pinouts and is intended for Table 1.
