Quad RS-422/RS-485 receiver for 3.3 V buses
The AM26LV32INSG4: The part integrates four independent receivers in a single package, each with 50 mV of built-in hysteresis to reject noise on long cable runs.
3.3 V supply — not a 5 V part
For 5V buses, a level translator or a 5V-tolerant receiver is needed.
50 mV hysteresis — noise immunity on the bus
The 50 mV receiver hysteresis is a key spec for industrial environments where cable pick-up and ground shifts can corrupt data. It provides a clean switching threshold without external Schmitt triggers, simplifying the BOM. For short, well-terminated links the hysteresis may be academic, but on a factory floor with long drops it makes the difference between a reliable link and intermittent errors.
Lifecycle: active, no obsolescence risk
The 'G4' suffix indicates a lead-free / RoHS-compliant finish, which is the current standard.
