MITSUBISHI SEMICONDUCTOR <TRANSISTOR ARRAY>
M54564P/FP
8-UNIT 500mA SOURCE TYPE DARLINGTON TRANSISTOR ARRAY
DESCRIPTION
PIN CONFIGURATION
M54564P and M54564FP are eight-circuit output-sourcing
Darlington transistor arrays. The circuits are made of PNP
and NPN transistors. Both the semiconductor integrated cir-
cuits perform high-current driving with extremely low input-
current supply.

FUNCTION
Package type 20P2N-A(FP)
The M54564P and M54564FP each have eight circuits,
which are made of input inverters and current-sourcing out-
puts. The outputs are made of PNP transistors and NPN
Darlington transistors. The PNP transistor base current is
constant. Resistance of 50kΩ is connected between each
output pin and GND, making these ICs suitable for fluores-
cent display tubes. VS and GND are used commonly among
the eight circuits.
