MITSUBISHI SEMICONDUCTOR <
TRANSISTOR ARRAY>
M54525AGP
7-UNIT 500mA DARLINGTON
TRANSISTOR-ARRAY WITH CLAMP DIODE
DESCRIPTION M54525AGP is seven-circuit Darlington
transistor array 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. PIN CONFIGURATION

FUNCTION The M54525AGP has seven circuits consisting of
NPN Darlington
transistors. This IC has resistance of 10.5kΩ and Zener diode between input
transistor bases and input pins. A spike-killer clamping diode is provided between each output pin (collector) and COM pin (pin 9). The output
transistor emitters are all connected to the GND pin (pin 8). The collector current is 500mA maximum. Collector-emitter sup...
