ULQ2801 - ULQ2802 ULQ2803 - ULQ2804 Eight Darlington array Features ■ ■ ■ ■ ■ ■ ■ ■ Eight Darlingtons per package Extended temperature range: -40 to 105 °C 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 DIP-18 Description The ULQ2801A-ULQ2804A each contain eight Darlington transistors with common emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600 mA (500 mA 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 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.
