MITSUBISHI SEMICONDUCTOR <
TRANSISTOR ARRAY>
M54523P/FP
7-UNIT 500mA DARLINGTON
TRANSISTOR-ARRAY WITH CLAMP DIODE
DESCRIPTION M54523P and M54523FP are seven-circuit Darlington
transistor 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 (BV CEO ≥ 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 elements (LEDs and lamps), and interfaces between standard MOS-bipolar logic IC FUNCTION The M54523P and M54523FP each have seven circuits consisting of
NPN Darlington
transistors. These ICs have resistance of 2.7k Ω 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 collector 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. PIN CONFIGURATION
