The DM74ALS258M has a total of 16 pins, which are assigned specific functions as follows:
The DM74ALS258M is a digital multiplexer that uses control inputs (A0 and A1) to select one of four input lines (B, C, D) and route it to the output line (Y). The enable input (E) must be active for the multiplexer to function. When E is low, the output is in a high-impedance state.
The DM74ALS258M can be used in various applications where multiple input signals need to be selectively routed to a single output line. Some potential application fields include:
These alternative models can be considered based on specific requirements or availability.
