概述

Description

Introduction to MAX487EEPA+ (concise)
- What it is: Maxim’s MAX487EEPA+ is a single-supply RS-485/RS-422 transceiver (half-duplex) in an 8-pin package, combining a differential driver and receiver for two-wire networks.
- Key features: typically powered from 4.75–5.25 V, with a failsafe/reliable receiver output when the bus is idle or faulted; enables for both the driver and receiver enable control; designed for robust operation in industrial environments.
- Variant notes: the “EPA” indicates the package type (8-pin) and “+” denotes an enhanced/extended version, often with an extended temperature range suitable for harsher conditions.
- Applications: industrial automation, motor controls, process control, building automation, and other RS-485/RS-422 networked systems.
- What to check: for exact data rates, input thresholds, bus strengths, power consumption, and pinout, consult the MAX487EEPA+ datasheet.
If you need, I can pull the specific electrical specs or compare it with similar transceivers.

Features

Here are concise features of MAX487EEPA+ (RS-485/RS-422 transceiver):
- Half-duplex RS-485/RS-422 transceiver
- 5V single-supply operation (typical 4.75V–5.25V)
- Data rates up to several Mbps (MAX487 family level)
- Fail-safe receiver: output goes high with open, shorted, or idle inputs
- Separate driver enable (DE) and receiver enable (RE) controls
- Robust protection: ESD protection on bus pins and bus-fault protection
- Wide bus/common-mode input range
- Low power consumption for dense networks
- 8-pin EPA+ package; RoHS-compliant; suitable for industrial temperature ranges (typical -40°C to +85°C)
Note: For exact figures (max data rate, bus protection specs, and temperature range), please refer to the MAX487EEPA+ datasheet.

Package

MAX487EEPA+ uses an 8-pin SOIC package with an exposed pad (SOIC-8 with EP).

Pinout

Pin count: 8 pins.
Function: An 8-pin RS-485/RS-422 transceiver. It provides a driver (DI to differential A/B) and a receiver (A/B to RO) with separate enables (DE for the driver, /RE for the receiver). Pins include A, B (bus lines), DI, RO, DE, /RE, Vcc, and GND.

Manufacturer

Manufacturer: Maxim Integrated (now part of Analog Devices, Inc.).
What kind of company: A US-based multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (now under Analog Devices).

Application

- Industrial automation and process control (RS-485/RS-422 bus)
- Building automation and HVAC systems
- Data acquisition and instrumentation networks
- Remote monitoring, telemetry, and smart-metering
- PLC/motor-control networks and other multi-point RS-485/RS-422 applications

Equivalent

MAX487EEPA+ is a 5V RS-485/RS-422 transceiver. Common equivalents from other vendors include:
- TI SN65HVD178 / SN65HVD178A
- ST SP485 / SP487
Note: exact cross-reference depends on package, unit load, data rate, and fail-safe options. Check distributor/manufacturer cross-reference tables for an exact match.
