概述

Description

ADM3486EARZ is Analog Devices’ low‑power, half‑duplex RS-485/RS-422 transceiver in an 8‑pin EARZ package. It combines a differential driver and receiver with pins for DI (data in), RO (data out), and control lines DE (driver enable) and RE (receiver enable). The bus pins are A and B for the differential pair. Key points:
- 1/4‑unit‑load on the RS‑485 bus; suitable for multi‑drop networks
- Fail‑safe receiver: RO goes high if the bus is idle, open, or shorted
- Single‑supply operation (typical 3.3–5.0 V), low quiescent current
- ESD protection on bus pins
- Data rates up to a few Mbps (typical for RS‑485 transceivers)
Common uses: interconnecting microcontrollers to industrial RS‑485 networks, building automation, and other serial‑bus applications. For exact electrical specs and pinout, consult the ADM3486 datasheet.

Package

ADM3486EARZ uses an 8-pin Small Outline IC (SOIC, N8) package, RoHS-compliant and lead-free.

Pinout

- Pin count: 8 pins (SOIC-8 package, ADM3486EARZ)
- Function: One-channel RS-485/RS-422 transceiver (half-duplex) with integrated driver and receiver. Pins: A, B (bus), DI (data input), RO (data output), DE (driver enable), /RE (receiver enable), VCC, GND.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
Company type: A US-based multinational semiconductor company specializing in analog, mixed-signal, and digital signal processing (DSP) integrated circuits for industrial, automotive, communications, and consumer markets.

Application

ADM3486EARZ is an RS-485/RS-422 transceiver. Typical application areas:
- Industrial automation and PLC networks
- Building automation (HVAC, lighting, security)
- Remote data acquisition and telemetry
- Multi-drop sensor networks and instrumentation
- Automotive/rail systems using RS-485/RS-422 buses
Used wherever robust, long-distance differential communication on a multi-point bus is required.
