Working Principles

The DM74AS32M is based on the Advanced Schottky (AS) logic family. It utilizes transistors and diodes to implement the logical OR function. When both input signals are low (0), the output is also low. If any of the input signals are high (1), the output becomes high. The propagation delay of 9ns indicates the time taken for the output to respond to a change in the input.
