8-UNIT 500mA DARLINGTON TRANSISTOR-ARRAY WITH CLAMP DIODE
DESCRIPTION
M54585KP is 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≥ 50V)
●
High-current driving (IC(max) = 500mA)
●
With clamping diodes
●
Driving available with TTL output or with PMOS IC output
●
With shrink small outline package
APPLICATION
Drives of relays and printers, digit drives of indication elements such as LEDs and lamps, and MOS-bipolar logic IC

FUNCTION
The M54585KP has eight circuits, which are NPN Darlington
transistors. Input transistors have resistance of 2.7kΩ be-

tween the base and input pin. A spike-killer clamping diode
is provided between each output pin and GND. Output transistor emitters are all connected to the GND pin.
Collector current is 500mA maximum. The maximum collector-emitter voltage is 50V.
