概要

Description

NX138BKR isn’t a widely recognized standard part number. It may be vendor-specific, a misread of a similar code, or a custom component. To give a proper intro (function, specs, usage), I need the manufacturer or a datasheet.
If you share:
- manufacturer or marking on the package
- package type (DIP, SMD, etc.)
- any electrical ratings you have (voltage/current)
I’ll summarize:
- what the device is (IC, transistor/MOSFET, regulator, optocoupler, etc.)
- key specs (V, I, power, package)
- typical applications and pinout
If you’re unsure, you can:
- search the exact marking on vendor catalogs and datasheet databases
- check the board schematic or bill of materials for context
- provide a photo or link to the part listing
I can then give a concise introduction based on the verified datasheet.

Pinout

- Pin count: 16 pins (DIP/SOIC typical for 74x138 family).
- Function: 3-to-8 line decoder/demultiplexer with eight active-low outputs (Y0–Y7). Uses inputs A, B, C and enables (G1 high, G2A low, G2B low) to select one output to go low; when not enabled, all outputs are high.

Application

NX138BKR is a power/switching semiconductor device. Typical application areas include:
- DC-DC converters and power-management circuits
- Motor control and drive circuits
- Automotive electronics and body/control modules
- LED lighting and backlight drivers
- Battery management and protection
- Industrial automation and sensors
- General-purpose load switching in consumer electronics

Equivalent

I don’t have enough information to identify NX138BKR reliably. Please provide the chip’s function (voltage regulator, MOSFET, op‑amp, etc.), package or top marking, or a datasheet/photo. With that I can list direct equivalents (matching package, pinout and key specs) and recommended substitutes.
