- Integral suppression diodes
- Versions for all popular logic families
- Output can be paralleled
- Inputs pinned opposite outputs to simplify board layout
Description
The ULN2801A, ULN2802A, ULN2803A and ULN2804A each contain eight Darlington transistors with mon emitters and integral suppression diodes for inductive loads. Each Darlington features a peak load current rating of 600 m A (500 m A 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 ULN2801A is designed for general purpose applications with a current limit resistor; the ULN2802A has a 10.5 kΩ input resistor and Zener for 14-25 V PMOS; the ULN2803A has a 2.7 kΩ input resistor for 5 V TTL and CMOS; the ULN2804A has a 10.5 kΩ 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
Table 1.
