Description The ULN2803A and ULN2804A 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. Four versions are available to simplify interfacing to standard logic families: the ULN2803A has a 2.7 kOhm input resistor for 5 V TTL and CMOS; the ULN2804A has a 10.5 kOhm input resistor for 6-15 V CMOS. All types are supplied in an 18-lead plastic DIP with a copper lead form and feature the convenient input-opposite-output pinout Features - Eight Darlington transistors 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 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2018-01-19 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2018-03-26 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2018-05-05 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2018-06-25 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2018-12-16 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2019-04-01 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2021-04-24 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2021-05-24 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2021-11-22 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2021-12-21 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2022-05-25 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2022-06-29 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2023-01-21 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2023-07-12 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2023-11-10 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2024-05-26 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2025-05-08 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2025-12-25 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2026-01-11 https://elecena.pl/product/13401549/uln2803a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2026-09-17
