概述

Description

MAX3488EESA+T is a Maxim Integrated (now Analog Devices) high‑speed, low‑power RS‑485/RS‑422 transceiver. It combines a differential driver and receiver in one 8‑pin package to support bidirectional two‑wire RS‑485 (and four‑wire RS‑422) networks. Key features:
- One driver and one receiver with 3‑state outputs (DE and /RE controls)
- Failsafe receiver output (known logic level when the bus is idle, open, or shorted)
- Suitable for industrial/long‑distance networks; robust ESD and short‑circuit protection
- Single‑supply operation (typical 3.3V–5V; common for RS‑485 transceivers)
- Extended temperature range (-40°C to +85°C) indicated by E; ESA indicates RoHS lead‑free packaging; +T indicates Tape & Reel
Common applications: industrial automation, building automation, PLCs, energy meters, and any RS‑485/RS‑422 point‑to‑multipoint networks.

Features

Here are key features of the MAX3488EESA+T (RS-485/RS-422 transceiver):
- Half‑duplex RS-485/RS-422 transceiver with DI/RO and DE/RE control
- 1/8 unit load on the bus (multipoint capability; up to 32 nodes on the network)
- Extended temperature option: -40°C to +85°C (E suffix)
- Tape & Reel packaging: +T suffix
- Wide bus common‑mode range and robust bus protection
- Failsafe receiver: RO outputs a known logic-high when the input is idle, open, or shorted
- Low-power operation with optional shutdown (DE/RE control)
- 8‑pin package (typical SOIC/MSOP) with rail‑to‑rail logic levels
- Bus pins protected against faults and ESD
- Data rates suitable for RS-485/422 applications (typical high-speed performance)
Note: Exact supply voltage, current figures, and max data rate can vary by device variant; refer to the datasheet for precise specifications.

Package

It’s an 8-pin surface-mount package (8‑pin SOIC), with tape‑and‑reel packaging (+T).

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC-8).
- Function: RS-485/RS-422 transceiver (single channel, typically half-duplex) with driver and receiver. Pins: DI (data in), RO (data out), DE (driver enable), /RE (receiver enable), A and B (differential bus), Vcc, GND.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI). Maxim Integrated is now part of ADI after their acquisition.
- What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits for various industries.

Application

- Industrial automation/control networks (RS-485/RS-422)
- PLCs and multi-point data acquisition
- Building automation and security systems
- Process instrumentation and telemetry
- Smart meters and energy monitoring
- Motor-control interfaces and remote sensor links over twisted pair
- Harsh-environment applications requiring extended temperature (-40°C to +85°C)
