DESCRIPTION
The L9222 monolithic quad transistor switch is designed for high current, high voltage switching applications.
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 transistor plus a clamp diode for applications with inductive loads.
​​​​​​​The emitters of the four switches are connected together 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.
