M54522WP
8-UNIT 400mA DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE
DESCRIPTION
M54522WP is an 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.
FEATURES
● High breakdown voltage (BVCEO > 40V)
● High-current driving (Ic(max) = 400mA)
● With clamping diodes
● Driving available with PMOS IC output
APPLICATIONS
Drives of relays and printers, digit drives of indication elements
(LEDs and lamps), and interfaces between microcomputer
output and high-current or high-voltage systems

FUNCTION
The M54522WP each have eight circuits consisting of NPN
Darlington transistors. This ICs have resistance of 20kΩ
between input transistor bases and input pins.
A spike-killer clamping diode is provided between each output
pin (collector) and COM pin. The output transistor emitters
are all connected to the GND pin (pin 9).
The collector current is 400mA maximum. Collector-emitter
supply voltage is 40V maximum.
