Technical information

The L6221A monolithic quad darlington 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 darlington transistor plus a fast diode for switching applications with inductive device loads. The emitters of the four switches are commoned. Any number of inputs and outputs of the same device may be paralleled.

• OUTPUT VOLTAGE UP TO 50 V
• OUTPUT CURRENT UP TO 1.8 A
• VERY LOW SATURATION VOLTAGE
