® U LN2801A ULN2802A - ULN2803A ULN2804A - ULN2805A EIGHT DARLINGTON ARRAYS . . . . . . . EIGHT DARLINGTONS WITH COMMON EMITTERS OUTPUT CURRENT TO 500 mA 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 DIP18 PIN CONNECTION ( top view) DESCRIPTION The ULN2801A-ULN2805A each contain eight darlington transistors with common emitters and integral suppression diodes for inductive loads. Each darlington features a peak load current rating of 600mA (500mA continuous) and can withstand at least 50V in the off state. Outputs may be paralleled for higher current capability. Five versions are available to simplify interfacing to standard logic families : the ULN2801A is designed for general purpose applications with a current limit resistor ; the ULN2802A has a 10.5kΩ input resistor and zener for 14-25V PMOS ; the ULN2803A has a 2.7kΩ input resistor for 5V TTL and CMOS ; the ULN2804A has a 10.5kΩ input resistor for 6-15V CMOS and the ULN2805A is designed to sink a minimum of 350mA for standard and Schottky TTL where higher output current is required. All types are supplied in a 18-lead plastic DIP with a copper lead from and feature the convenient inputopposite-output pinout to simplify board layout.
