M54522P and M54522FP are eight-circuit Darlington transistor arrays with clamping diodes. The circuits are made of NPN transistors. Both the semiconductor integrated circuits perform high-current driving with extremely low input-current supply. FUNCTION The M54522P and M54522FP each have eight circuits consistingof NPN Darlington transistors. These ICs have resistanceof 20kΩ between input transistor bases and input pins.A spike-killer clamping diode is provided between each outputpin (collector) and COM pin. The output transistor emittersare all connected to the GND pin (pin 8).The collector current is 400mA maximum. Collector-emittersupply voltage is 40V maximum.The M54522FP is enclosed in a molded small flat package,enabling space-saving design.
