Additional Details:

The DM5407J/883QS is typically supplied in a ceramic DIP (Dual In-line Package) for enhanced durability. The operating temperature range is typically -55°C to +125°C, making it suitable for extreme environments. The open-collector outputs require external pull-up resistors to define the high logic level. The value of the pull-up resistor should be chosen based on the load current and the desired switching speed.
