MITSUBISHI SEMICONDUCTOR <TRANSISTOR ARRAY>
M54564P/FP
8-UNIT 500mA SOURCE TYPE DARLINGTON TRANSISTOR ARRAY
DESCRIPTION
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.
FEATURES
High breakdown voltage (BVCEO ≥ 50V)
High-current driving (Io(max) = –500mA)
With output pulldown resistance (Driving available with
fluorescent display tube)
Driving available with PMOS IC output or with TTL output
Wide operating temperature range (Ta = –20 to +75°C)
Output current-sourcing type
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 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.
Output current is 500mA maximum. Supply voltage VS is 50V
maximum.
The M54564FP is enclosed in a molded small flat package,
enabling space-saving design.
