DESCRIPTION

The L9222 monolithic quad transistor switch is de-

signed for high current, high voltage switching ap-

plications.

Each of the four switches is controlled by a logic

input and all four are controlled by a common en-

able input. All inputs are TTL-compatible for direct

connection to logic circuits. Each switch consists

of an open-collector transistor plus a clamp diode

for applications with inductive loads.

The emitters of the four switches are connected to-

gether to GND. The switches of the same device

may be paralled. The device is intended to drive

coils such as relays, solenoids, unipolar stepper

motors, LED etc.
