L9222
DESCRIPTION
The L9222 monolithicquad transistorswitch is designedforhighcurrent,highvoltageswitchingapplications.
Eachof the fourswitchesis controlledby a logicinput andallfour are controlledby a commonenable
input. All inputs are TTL-compatiblefor direct connectionto logic circuits. Each switch consistsofan
open-collectortransistorplus a clamp diode for applicationswith inductiveloads.

ORDERING NUMBER : L9222
Theemitters ofthe four switches areconnectedtogether to GND. The switches of the same device
may be paralled. The device is intended to drive
coilssuchas relays,solenoids,unipolarsteppermotors,LED etc.
