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.
