MITSUBISHI SEMICONDUCTOR <TRANSISTOR ARRAY>
M54531P/FP
7-UNIT 400m A DARLINGTON TRANSISTOR ARRAY WITH CLAMP DIODE
DESCRIPTION
M54531P and M54531FP are seven-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
ÁHigh breakdown voltage (BV CEO ≥ 40V)
ÁHigh-current driving (Ic(max) = 400mA)
ÁWith clamping diodes
ÁDriving available with PMOS IC output
ÁWide input voltage range (VI = –40 to +40V)
ÁW ide operating temperature range (Ta = –20 to +75°C)
APPLICATION
Drives of relays and printers, digit drives of indication ele-
ments (LEDs and lamps), and MOS-bipolar logic IC inter-
faces
FUNCTION
The M54531P and M54531FP each have seven circuits con-
sisting of NPN Darlington transistors. A serial circuit includ-
ing a diode and resistance of 20k Ω is provided between in-
put transistor bases and input pins. A spike-killer clamping
diode is provided between each output pin (collector) and
COM pin (pin 9). The output transistor emitters are all con-
nected to the GND pin (pin 8).
The collector current is 400mA maximum. Collector-emitter
supply voltage is 40V maximum.
The M54531FP is enclosed in a molded small flat package,
enabling space-saving design.
