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/21699527/uln2804a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2022-09-25 https://elecena.pl/product/21699527/uln2804a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2022-10-20 https://elecena.pl/product/21699527/uln2804a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2023-01-14 https://elecena.pl/product/21699527/uln2804a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2023-08-25 https://elecena.pl/product/21699527/uln2804a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2024-03-13 https://elecena.pl/product/21699527/uln2804a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2024-07-02 https://elecena.pl/product/21699527/uln2804a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2026-01-21 https://elecena.pl/product/21699527/uln2804a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2026-02-11 https://elecena.pl/product/21699527/uln2804a-eight-darlington-trans-arrays-npn-50-v-0-5-a-dip-18 2026-03-07
