概述

Description

MAX1487CPA+ is a Maxim Integrated (now Analog Devices) isolated serial transceiver. It provides galvanic isolation between two digital domains while transferring high‑speed serial data across an isolation barrier. The device typically includes a transmitter and receiver on opposite sides of the barrier, plus isolated supply pins and protection features (ESD, fault indication, overcurrent/overvoltage protection). The CPA+ suffix denotes a specific package/temperature variant and affects packaging and operating conditions, not the core function. Typical applications include systems that require safe data transfer across an isolation boundary in industrial, automotive, or medical equipment—such as isolated microcontroller interfaces, isolated sensors, and robust data links. For exact specs (data rate, isolation voltage, supply rails, package options, and ordering code), consult the latest MAX1487CPA+ datasheet or distributor page.

Package

MAX1487CPA+ comes in an 8-pin Small Outline package (SOIC-8), RoHS-compliant.

Pinout

8 pins (CPA+ package). Function: half-duplex RS-485/RS-422 transceiver with bus driver and receiver. Pinout includes A and B (bus), DI (driver input), RO (receiver output), DE (driver enable), /RE (receiver enable, active low), Vcc, GND. Provides tri-statable driver and receiver for differential multi-drop networks.
