Other Parts Discussed in Thread: TCA8418, LM8330, LM8333, TCA8418E

Hi team,

Do we have alternative for ADP5585ACPZ, which is a Keypad Decoder and I/O Expansion?

Regards,

    Hailiang,

    We have four keypad scan options: TCA8418, TCA8418E, LM8330, and LM8333. These would not be identical drop-in replacements, but they would be the closest matches.

    From a quick look at the third-party part you mentioned, it looks like TCA8418 could be a good match, but check the others as well.

    Best,

    Danny
