Description

MAX1483ESA is a Maxim Integrated RS-485/RS-422 transceiver. It combines a differential bus driver and a differential receiver in a compact package (ESA suffix indicates the 8‑pin package/extended temperature).
Key points:
- Interfaces a microcontroller to a twisted-pair RS-485/RS-422 network
- Uses DE (driver enable) and RE (receiver enable) pins for control
- Differential TXD/RXD signals with fail-safe receiver (guaranteed logic-high if the bus is idle or open)
- Supports multi-point RS-485 and point-to-point RS-422/RS-485 configurations
- Features bus protection (short-circuit/ESD) and reasonable power for embedded/industrial use
Typical applications:
- Industrial automation and process control
- Building and home automation
- Remote sensing and data acquisition networks
Quick usage:
- Connect A/B to the differential bus
- Drive DE high to transmit, low to receive
- Enable/disable the receiver with RE
- Add proper biasing on idle bus if needed; consult the datasheet for exact electrical specs and data rate limits.

Features

Here are typical features of the MAX1483ESA (RS-485/RS-422 transceiver family; ESA indicates extended temperature/package):
- RS-485/RS-422 transceiver with DI/DE/RE control (3-state outputs)
- Half-duplex operation with a single differential pair (A/B bus)
- 1/4 unit-load on the bus for multi-drop networks
- Fail-safe receiver: RO goes high when A and B are open, shorted, or idle
- Wide bus/common‑mode range with robust noise immunity
- ESD protection on the bus pins
- Suitable for high-speed data paths (typical up to 10 Mbps)
- Low quiescent current; supports low-power/shutdown modes
- Extended temperature range (ESA: −40°C to +125°C) for harsh environments
- Single-supply operation in common logic levels; available in 16-pin ESA package
Note: Exact voltage range, data rate, and package details should be confirmed from the specific datasheet for your device revision.

Package

16-pin surface-mount package (SOIC-16).

Pinout

8-pin package. It’s a half‑duplex RS‑485/RS‑422 transceiver (DI to RO with DE and /RE controls; A and B to the differential bus; Vcc and GND).
