OUTPUT CURRENT UP TO 1.8 A | Vcc 50V | DIP16 package
- Manufacturer: STMicroelectronics
- Package: DIP16
- Product Family: QUAD DARLINGTON SWITCH IC
- OUTPUT VOLTAGE UP TO 50 V
- The L6221A is full compatible (REPLACEMENT) to UDN2540B (Allegro)
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.
