M54561P
7-UNIT 300mA SOURCE TYPE DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE
DESCRIPTION
M54561P is seven-circuit output-sourcing Darlington transis-
tor arrays. The circuits are made of PNP and NPN transis-
tors. Both the semiconductor integrated circuits perform
high-current driving with extremely low input-current supply.
FEATURES
q High breakdown voltage (BVCEO ≥ 40V)
q High-current driving (Io(max) = –300mA)
q With output clamping diodes
q Active “L” input
q Wide operating temperature range (Ta = –20 to +75°C)

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