概要
Description
MAX3483EESA is Maxim Integrated’s RS-485/RS-422 transceiver. It provides a differential driver and receiver for two-wire RS-485 or four-wire RS-422 networks, enabling robust long‑distance serial communication on industrial and automation systems.
Key points:
- Single‑supply operation (commonly 3.3V) with low power consumption.
- Driver enable (DE) and receiver enable (/RE) control; RO and DI interface for easy microcontroller integration.
- Differential signaling for noise immunity and multi‑drop networks; suitable for long cable runs.
- Fail‑safe receiver output (RO) to a known state when the inputs are open, shorted, or idle.
- Bus protection features and ESD protection on the line pins; suitable for harsh environments.
- Package suffix EESA indicates a specific package and temperature/lead‑free variant chosen by the supplier.
Applications include industrial control, building automation, instrumentation, and other RS‑485/RS‑422 networks. For exact electrical specs, data rate, and the precise meaning of the EESA suffix for your part variant, consult the MAX3483EESA datasheet.
