FUNCTION
OUTPUT
The M54522FP each have eight circuits consisting of NPN
20K
Darlington transistors. This ICs have resistance of 20kΩ
INPUT
between input transistor bases and input pins.
A spike-killer clamping diode is provided between each output
20K
pin (collector) and COM pin. The output transistor emitters
are all connected to the GND pin (pin 10).
2K
The collector current is 400mA maximum. Collector-emitter
GND
supply voltage is 40V maximum.
The eight circuits share the COM and GND.
The diode, indicated with the dotted line, is parasitic, and
cannot be used.
