Additional Details

The DM5406J/883C is typically supplied in a ceramic dual-in-line package (CERDIP), offering superior hermeticity and resistance to environmental factors. The /883C designation signifies compliance with MIL-STD-883, ensuring the device meets rigorous quality and reliability standards.

Each inverting buffer inverts the input signal at its output. The open-collector output requires an external pull-up resistor to define the high-level output voltage. The value of the pull-up resistor depends on the load current and the desired switching speed. The DM5406J/883C is used in applications where high reliability and the ability to drive high-voltage or high-current loads are essential. It also facilitates the implementation of wired-AND logic functions by connecting the open-collector outputs of multiple gates together. Requires a 5V power supply for operation.
