MITSUBISHI SEMICONDUCTOR <TRANSISTOR ARRAY>
M54587P/FP
8-UNIT 500mA DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE
DESCRIPTION
M54587P and M54587FP are eight-circuit collector-current-
synchronized Darlington transistor arrays. The circuits are
made of PNP and NPN transistors. Both the semiconductor
integrated circuits perform high-current driving with ex-
tremely low input-current supply.
FEATURES
G
High breakdown voltage (BV
CEO
≥
50V)
G
High-current driving (I
C(max)
= 500mA)
G
“L” active level input
G
With input diode
G
With clamping diodes
G
Wide operating temperature range (Ta = –20 to +75
°
C)
APPLICATION
Interfaces between microcomputers and high-voltage, high-
current drive systems, drives of relays and MOS-bipolar logic
IC interfaces
FUNCTION
The M54587 is produced by adding PNP transistors to
M54585 inputs. Eight circuits having active L-level inputs are
provided.
Resistance of 7k
and diode are provided in series between
each input and PNP transistor base. The input diode is in-
tended to prevent the flow of current from the input to the
V
CC
. Without this diode, the current flow from “H” input to the
V
CC
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 out-
put especially for the driver of current sink.
Collector current is 500mA maximum. Collector-emitter sup-
ply voltage is 50V.
The M54587FP is enclosed in a molded small flat package,
enabling space saving design.
