MAX931ESA

MAX931ESA is a Maxim Integrated (now part of Analog Devices) high-speed, low-power differential line receiver/transceiver in the MAX931 family. It accepts a differential input signal and converts it to a TTL/CMOS logic-level single-ended output, making it suitable for interfacing differential serial links (e.g., RS-422/RS-485, LVDS-to-TTL bridges) with standard logic circuits.
Key points:
- Differential input with robust common‑mode range
- Single-supply operation (typical 3–5.5 V)
- Fail-safe behavior (defined output when inputs are open/shorted)
- Low-power, compact packaging (ESA suffix indicates RoHS-compliant packaging)
- Used in data communications, industrial networks, automotive and instrumentation interfaces
For exact electrical specs, operating conditions, and package details, refer to the current MAX931ESA datasheet on Analog Devices/Maxim’s website. If you need a quick comparison or recommended replacement, share your target supply, voltage levels, and environment.

Pin count: 8 pins.
Function: Differential RS-485/RS-422 transceiver (one driver and one receiver). Pins include Vcc, GND, DI (driver input), RO (receiver output), DE (driver enable), /RE (receiver enable), and the bus lines A and B.

Manufacturer: Maxim Integrated (now part of Analog Devices).
What kind of company: A semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (interfaces, data converters, amplifiers, power management, sensors, etc.).

MAX931ESA is a differential line driver/receiver suitable for balanced serial links. Common application areas include:
- RS-422/RS-485 serial communication networks
- Industrial automation and control systems
- Data-communication equipment (modems, repeaters, interface cards)
- Backplane and board‑to‑board high-speed interconnects
- Automotive in-vehicle networks and other differential-signaling systems
- Telemetry, instrumentation, and test/measurement equipment
These cover general uses that require robust differential signaling over cables or backplanes.

MAX931ESA comes in an 8-pin SOIC (small-outline) package, RoHS-compliant (Pb-free).
