ULQ2801A ULQ2802A - ULQ2803A ULQ2804A - ULQ2805A EIGHT DARLINGTON ARRAYS . . . . . . . . EIGHT DARLINGTONS PER PACKAGE EXTENDED TEMPERATURE RANGE (– 40 to 105°C) OUTPUT CURRENT TO 500mA OUTPUT VOLTAGE TO 50V INTEGRAL SUPPRESSION DIODES VERSIONS FOR ALL POPULAR LOGIC FAMILIES OUTPUT CAN BE PARALLELED INPUTS PINNED OPPOSITE OUTPUTS TO SIMPLIFY BOARD LAYOUT DIP18 (Plastic Package) DESCRIPTION The ULQ2801A-ULQ2805Aeach 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 ULQ2801A is designed for general purpose applications with a current limit resistor ; the ULQ2802Ahas a 10.5kΩ input resistor and zener for 14-25V PMOS ; the ULQ2803A has a 2.7kΩ input resistor for 5V TTL and CMOS ; the ULQ2804A has a 10.5kΩ input resistor for 6-15V CMOS and the ULQ2805A 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 frame and feature the convenient input-opposite-outputpinout to simplify board layout.
