L6221

Quad Darlington switch

Features

■ Four non-inverting inputs with enable

■ Output voltage up to 50 V

■ Output current up to 1.8 A

■ Very low saturation voltage

■ TTL compatible inputs

■ Integral fast recirculation diodes

Applications

The L6221 monolithic quad Darlington switch is

designed for high current, high voltage switching

applications.

Description

Each of the four switches is controlled by a logic

input and all four are controlled by a common

enable input. All inputs are TTL-compatible for

direct connection to logic circuits.

Each switch consists of an open-collector

Darlington transistor plus a fast diode for

switching applications with inductive device loads.

The emitters of the four switches are commoned.

Any number of inputs and outputs of the same

device may be paralleled.
