Product Overview
ULN2803A is an eight-Darlington array. It contains eight Darlington transistors with common emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600mA (500mA continuous) and can withstand at least 50V in the OFF state. Outputs may be paralleled for higher current capability.
- Eight Darlington transistors with common emitters
- Integral suppression diodes
- Output can be paralleled
- Inputs pinned opposite outputs to simplify board layout
- DIP-18 package
- Output leakage current is 50µA max at TA = 70°C, VCE = 50V
- DC forward current gain is 1000 for ULN2801A, VCE = 2V, IC = 350mA
- Turn-on delay time/turn-off delay time is 0.25µs typ at 0.5VI to 0.5VO
- Input capacitance is 15pF typical
- Operating ambient temperature range from -20 to 85°C
