MITSUBISHI SEMICONDUCTOR <
TRANSISTOR ARRAY>
M54561P
7-UNIT 300mA SOURCE TYPE DARLINGTON
TRANSISTOR ARRAY WITH CLAMP DIODE
DESCRIPTION M54561P is seven-circuit output-sourcing 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. PIN CONFIGURATION (TOP VIEW)

FUNCTION The M54561P have seven circuits of current-sourcing outputs. Darlington
transistor, which are made of
PNP transistor and
NPN transistor. Resistance of 20kΩ is connected between
PNP transistor base and input pin.
PNP transistor emitters and
NPN transistor collector is connected V S (pin 8), and spike killer clamping diode is provided between each www.DataSheet4U.com output pins. Output currene is 300mA maximum and supply voltage VS is 40V maximum operate Active “L” input.
