AM26C31MWB

AM26C31MWB is a CMOS logic IC from AMD’s AM26C31 family. It’s a multi-channel device used for data routing/selection in digital systems (the exact function—such as a multiplexer/demultiplexer or bus driver—depends on the specific variant and wiring). It typically runs from a 5V supply and accepts CMOS/TTL-compatible inputs, with standard CMOS-style outputs and a control enable or 3-state option depending on the version. The MWB suffix denotes a particular package/temperature rating variant (e.g., a specific DIP/SMD package and operating range). For precise function, pinout, timing, and electrical specs, consult the datasheet for the exact part revision. If you can share the exact function you need (e.g., mux, demux, or bus transceiver), I can give a tighter summary.

AM26C31MWB is a quad differential line receiver (RS-422/RS-423 compatible) in an MWB package. Key features:
- Four differential input channels with TTL/CMOS-compatible single-ended outputs
- Operates from a 5V supply
- Wide input common‑mode range for reliable RS-422/RS-423 operation
- Failsafe outputs: defined logic level when inputs are open or shorted
- High noise immunity and robust common-mode rejection
- ESD protection on inputs; low-power CMOS design
- Suitable for high-speed, multi-drop differential buses and long-distance links
Note: For exact electrical specs (propagation delay, input thresholds, current consumption, package pinout), consult the current datasheet.

- Pin count: 16 pins (MWB package).
- Function: Quad 2-to-1 data selector (multiplexer). Four data paths (A0–A3 and B0–B3) are independently routed to outputs Y0–Y3 under a common 2-bit select INPUT (S1, S0).

- Manufacturer: Advanced Micro Devices, Inc. (AMD).
- What kind of company: An American multinational semiconductor company that designs and manufactures integrated circuits (ICs), including microprocessors, graphics processors, memory, and other logic devices for computers and embedded systems.

AM26C31MWB is a quad differential line receiver for RS-422/RS-423 interfaces. Typical applications include:
- Differential data reception and level conversion to TTL/CMOS for microprocessors.
- Industrial automation, remote telemetry, and factory-floor networks (high noise immunity, longer runs).
- Multipoint data links and computer peripherals (printers, terminals) using RS-422/RS-423 buses.
- Interfaces in data-acquisition and instrumentation front-ends requiring multiple differential channels.
- Any system needing four independent differential receivers with good EMI rejection and bus-sharing capability.

It’s a 16-pin molded wide-body surface-mount package (SOIC).
