M54523P/FP
7-UNIT 500mA DARLINGTON TRANSISTOR-ARRAY WITH CLAMP DIODE
DESCRIPTION
M54523P and M54523FP 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
q High breakdown voltage (BVCEO ≥ 50V)
q High-current driving (IC(max) = 500mA)
q _{With clamping diodes}
q Driving available with PMOS IC ouput
q _{Wide operating temperature range (Ta = –20 to +75°C)}
APPLICATION
Drives of relays and printers, digit drives of indication ele-
ments (LEDs and lamps), and interfaces between standard
MOS-bipolar logic IC
FUNCTION
The M54523P and M54523FP each have seven circuits con-
sisting of NPN Darlington transistors. These ICs have resis-
tance of 2.7kΩ between input transistor bases and input
pins. A spike-killer clamping diode is provided between each
output pin (collector) and COM pin. The output transistor
emitters are all connected to the GND pin (pin 8). The col-
lector current is 500mA maximum. Collector-emitter supply
voltage is 50V maximum.The M54523FP is enclosed in a
molded small flat package, enabling space-saving design.
