Specific Comments and Questions

Disclaimer: Specifications are for reference. Always verify with the manufacturer's latest documentation before production. The Ultimate Guide to "My 9892 Datasheet": Specifications,

• Fix: Increase the input current to 15mA (use a 220-ohm resistor) or replace the IC.

Scenario B: Isolated Digital Input (using 9892 optocoupler)

• Microcontroller reads a 24V industrial sensor.
• 9892 input: 1kΩ resistor in series with LED. Current = ~10mA.
• Output: 10kΩ pull-up to 3.3V. Microcontroller pin reads low when sensor is active.

The Final Polish: The "92" represented the 92nd day of continuous stress testing that proved the design was flawless. A Legacy in Print

However, there are two very common component series that are likely what you are looking for: the LM9892 (or LM8982) or the TDA9892.
