M54583P and M54583FP are eight-circuit collector-currentsynchronized 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
APPLICATION
Interfaces between microcomputers and high-voltage, highcurrent 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
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 output especially for the driver of current sink.
Collector current is 400mA maximum. Collector-emitter supply voltage is 50V.
The 54583FP is enclosed in a molded small flat package,
enabling space saving design.
