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.

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.
