Visão Geral

Description

MAX487EESA is a Maxim Integrated RS-485/RS-422 transceiver. It provides a low‑power, half‑duplex differential driver and receiver that run from a single supply (typical 5 V). Key features include DE/RE control for driver enable and receiver enable, tri‑state outputs, and a fail‑safe receiver so RO stays high when the bus is idle/open/shorted. It also offers protection on the A/B lines and comes in an 8‑pin package with RoHS/extended‑temperature options (suffix EESA). Typical applications are industrial automation, building automation, and other RS‑485/RS‑422 network segments. For exact electrical specs, pinout, and packaging, refer to the latest MAX487EESA datasheet.

Pinout

Pin count: 8 pins.
Function: MAX487EESA is an RS-485/RS-422 transceiver (one-channel, half‑duplex) with driver and receiver. Pins include DI (data in), RO (data out), DE (driver enable), RE (receiver enable), A and B (bus lines), Vcc, and GND (extended-temperature variant in ESA packaging).

Manufacturer

MAX487EESA is manufactured by Maxim Integrated Products (MAXIM). Maxim is a semiconductor company that designs and manufactures analog and mixed-signal integrated circuits; it is now a wholly owned subsidiary of Analog Devices.

Application

MAX487EESA is an RS-485/RS-422 transceiver. Common application areas include:
- Industrial automation and process control networks (PLC, DCS, remote I/O)
- Building automation, HVAC, and energy-management systems
- Data acquisition, instrumentation, and test equipment with multi-point serial links
- Point-to-point or multipoint RS-485/RS-422 networks over moderate to long distances
- Telemetry, remote monitoring and control, gateways, and sensor networks
These use cases leverage robust differential signaling, multi-point capability, and 5V operation typical of RS-485/RS-422 transceivers.

Package

An 8-pin SOIC (Small-Outline) surface-mount package; RoHS-compliant/lead-free.
