L9222
QUAD INVERTING TRANSISTOR SWITCH
..... OUTPUT VOLTAGE TO 50V
OUTPUT CURRENT TO 1.2A
VERY LOW SATURATION VOLTAGE
TTL COMPATIBLE INPUTS
INTEGRAL SUPPRESSION DIODE
DE SCRI PT I O N
The L9222 monolithic quad transistor switch is de-
signed for high current, high voltage switching appli-
cations.
Each of the four switches is controlled by a logic in-
put and all four are controlled by a common enable
input. All inputs are TTL-compatible for direct con-
nection to logic circuits. Each switch consists of an
open-collector transistor plus a clamp diode for ap-
plications 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
coilssuch as relays, solenoids,unipolar steppermo-
tors, LED etc.
