My 9892 Datasheet Verified (2026)

Search result shows “9892A” datasheet. You have “9892C”. The “A” version has different pin 7 function (shutdown vs. no connection). If you use the wrong one, your circuit oscillates.

Solution: Demand an exact match on ALL suffix letters.

Yes. The 9892 is a verified, low-threshold P-Channel MOSFET. my 9892 datasheet verified

You can confidently use this for:

Do not use this for:

In many service manuals and BOMs (Bills of Materials), “9892” refers to a variant of the National Semiconductor (now Texas Instruments) LM series. An LM9892 is often a dual operational amplifier or a voltage comparator with specific temperature range and offset voltage characteristics. Unverified datasheets for this part often confuse it with the LM393 or LM358, leading to pinout mismatches.

What board is this from? What are the surrounding components? Search result shows “9892A” datasheet

This context allows you to reject obviously wrong datasheets. If the board runs at 12V and a candidate datasheet says absolute max 5.5V – discard immediately.

If verification shows the 9892 is a 74HC9892 hex inverter, the verified datasheet provides: Do not use this for: In many service

Using an LS (low-power Schottky) datasheet for an HC (high-speed CMOS) part would overestimate power consumption by 10x.

The first hurdle with my 9892 datasheet verified is that “9892” is rarely a complete part number. It is typically a partial marking, a date code, or a lot code. Through years of component analysis, three primary candidates emerge:
