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.
