M54585KP

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-cur-

rent driving with extremely low input-current supply.

FEATURES

q High breakdown voltage (BVCEO ≥ 50V)

q High-current driving (IC(max) = 500mA)

q With clamping diodes

q Driving available with TTL output or with PMOS IC output

q With shrink small outline package

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 tran-

sistor emitters are all connected to the GND pin.

Collector current is 500mA maximum. The maximum collec-

tor-emitter voltage is 50V.

3k

GND

The eight circuits share the COM and GND.

The diode, indicated with the dotted line, is parasitic, and cannot

be used.
