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.
