The M54585P/FP is an 8-channel 500mA Zener diode clamped Darlington transistor array with extremely low input current consumption.
The M54585P/FP is an eight‑circuit Darlington transistor array with integrated clamping diodes. Each circuit uses NPN transistors and provides high‑current driving capability while maintaining low input current. The device is suited for driving relays, printers, LEDs, lamps, and MOS‑bipolar logic interfaces.
The datasheet lists absolute maximum ratings, recommended operating conditions, and electrical characteristics such as a 50 V collector‑emitter breakdown voltage, 500 mA per‑circuit collector current, and operation from –20 °C to +75 °C. Two package options are offered: a flat molded package (FP) and a standard 18‑pin package (P).
