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

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)

APPLICATION

Drives of relays, printers, LEDs, fluorescent display tubes

and lamps, and interfaces between MOS-bipolar logic sys-

tems and relays, solenoids, or small motors

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 20k

Ω is connected be-

tween PNP transistor base and input pin. PNP transistor

and spike killer clamping diode is provided between each

output pins.

40V maximum operate Active “L” input.
