Descriptions:

The M54544L is a monolithic integrated circuit containing seven high-voltage, high-current Darlington transistor arrays. Each channel consists of an open-collector Darlington pair with common emitter and suppression diodes for inductive loads. It is designed for interfacing between low-level logic circuits and high-power loads such as relays, solenoids, and lamps.

Features:

  • High-Voltage Outputs (50V)
  • High-Current Sinking Capability (500mA per Channel)
  • TTL/CMOS-Compatible Inputs
  • Internal Clamp Diodes for Inductive Load Protection
  • Wide Operating Temperature Range
  • Reliable for Industrial and Automotive Applications

This IC is commonly used in applications requiring multiple high-power switching functions controlled by low-power logic circuits.
