2878 Datasheet (Allegro MicroSystems) - QUAD HIGH-CURRENT DARLINGTON SWITCHES

2878, QUAD HIGH-CURRENT DARLINGTON SWITCHES

2878 AND 2879 QUAD HIGH-CURRENT DARLINGTON SWITCHES These quad Darlington arrays are designed to serve as interface between low-level logic and peripheral power devices such as solenoids, motors, incandescent displays, heaters, and similar loads of up to 320 W per channel.

Both integrated circuits include transient-suppression diodes that enable use with inductive loads.

The input logic is compatible with most TTL, DTL, LSTTL, and 5 V CMOS logic.

Type UDN2878W and UDN2879W 4 A arrays are identi
