ULQ2801, ULQ2802, ULQ2803, ULQ2804 Eight Darlington arrays Datasheet - production data 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 DIP-18 to standard logic families: the ULQ2801A is designed for general purpose applications with a current limit resistor the ULQ2802A has a 10.5 k input resistor and zener for 14-25 V PMOS the ULQ2803A has a 2.7 k input resistor Features for 5 V TTL and CMOS the ULQ2804A has a 10.5 k input resistor for 6-15 V CMOS. Eight Darlingtons per package All types are supplied in a 18-lead plastic DIP with Extended temperature range: -40 to 105 C a copper lead from and feature the convenient Output current to 500 mA input-opposite-output pinout to simplify board Output voltage to 50 V layout. Integral suppression diodes Versions for all popular logic families Output can be paralleled Inputs pinned opposite outputs to simplify board layout Table 1.
