ULQ2803 Datasheet | STMicroelectronics

Features - Eight Darlingtons per package - Extended temperature range: -40 to 105 °C - Output current to 500 m A - Output voltage to 50 V - Integral suppression diodes - Versions for all popular logic families - Output can be paralleled - Inputs pinned opposite outputs to simplify board layout Description The ULQ2801A-ULQ2804A each contain eight Darlington transistors with mon emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600 m A (500 m A continuous) and can withstand at least 50 V in the off state. Outputs may be paralleled for higher current capability. Five versions are available to simplify interfacing to standard logic families: the ULQ2801A is DIP-18 designed for general purpose applications with a current limit resistor; the ULQ2802A has a 10.5 kΩ input resistor and zener for 14-25V PMOS; the ULQ2803A has a 2.7 kΩ input resistor for 5 V TTL and CMOS; the ULQ2804A has a 10.5 kΩ input resistor for 6-15 V CMOS. All types are supplied in a 18-lead plastic DIP with a copper lead from and feature the convenient input-opposite-output pinout to simplify board layout. Table 1.
