PIN CONFIGURATION
MITSUBISHI SEMICONDUCTOR <TRANSISTOR ARRAY>
M54585P/FP
8-UNIT 500mA DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE
DESCRIPTION
M54585P and M54585FP are eight-circuit Darlington tran-
sistor arrays with clamping diodes. The circuits are made of
NPN transistors. Both the semiconductor integrated circuits
perform high-current driving with extremely low input-current
supply.
FEATURES
High breakdown voltage (BVCEO
≥ 50V)
High-current driving (Ic(max) = 500mA)
With clamping diodes
Driving available with TTL output or with PMOS IC output
Wide operating temperature range (Ta = –20 to +75
°C)
APPLICATION
Drives of relays and printers, digit drives of indication ele-
ments such as LEDs and lamps, and MOS-bipolar logic IC
interfaces
FUNCTION
The M54585P and M54585FP each have eight circuits,
which are NPN Darlington transistors. Input transistors have
resistance of 2.7k
Ω between the base and input pin. A spike-
killer clamping diode is provided between each output pin
and GND. Output transistor emitters are all connected to the
GND pin.
Collector current is 500mA maximum. The maximum collec-
tor-emitter voltage is 50V.
The M54585FP is enclosed in a molded small flat package,
enabling space-saving design.
