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.
