Description
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.
