M54583WP
8-UNIT 400mA DARLIGNON TRANSISTOR ARRAY
DESCRIPTION
M54583WP is eight-circuit collector-current sink type
Darlington transistor arrays. The circuits are made of PNP
and 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) = 400mA)
● Active L-level input
● With input clamping diodes
APPLICATIONS
Interfaces between microcomputers and high-voltage,
high current drive systems, drives of relays and printers,
and MOS-bipolar logic IC interfaces

FUNCTION
The M54583 is produced by adding PNP transistors to
M54523 inputs. Eight circuits having active L-level inputs
are provided.
Resistance of 7kΩ and diode are provided in series
between each input and PNP transistor base. The input
diode is intended to prevent the flow of current from the
input to the VCC. Without this diode, the current flow from
“H” input to the VCC and the “L” input circuits is activated,
in such case where one of the inputs of the 8 circuits is
“H” and the others are “L” to save power consumption.
The diode is inserted to prevent such misoperation.
This device is most suitable for a driver using NMOS IC
output especially for the driver of current sink.
Collector current is 400mA maximum. Collector-emitter
supply voltage is 50V.
