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 kO input resistor and zener for 14-25V PMOS; the ULQ2803A has a 2.7 kO input resistor for 5 V TTL and CMOS; the ULQ2804A has a 10.5 kO 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. https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2020-06-13 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2021-04-05 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2021-05-22 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2021-12-06 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2022-01-22 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2022-02-08 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2022-04-18 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2022-06-10 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2022-06-22 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2022-07-05 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2023-09-26 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2024-01-05 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2024-01-22 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2024-03-26 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2024-11-17 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2025-01-02 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2025-01-29 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2025-06-13 https://elecena.pl/product/16969006/ulq2801a-eight-darlington-array 2025-07-10
