概述

Description

MAX488EPA is a single‑channel RS‑485/RS‑422 differential transceiver from Maxim Integrated. It enables robust two‑wire (half‑duplex) or multi‑drop serial communication over differential A/B lines on industrial networks.
Key points:
- Differential driver (DI) and receiver (RO) with bus lines A and B
- DE and RE control pins for driver/receiver enable
- 5V operation with low quiescent current
- High‑speed data rate capability (Mbps range)
- Failsafe receiver output (RO remains high when the bus is idle, open, or shorted)
- Protects against typical transceiver faults and includes ESD protection on the bus pins
- Packaged in a compact 8‑pin form factor (suffix indicates packaging/temperature/ RoHS variant)
Typical uses: industrial automation, PLCs, building automation, and sensor networks. For exact electrical specs, timing, and package details, consult the MAX488EPA datasheet.

Equivalent

MAX488EPA is a 5V RS-485/RS-422 transceiver. Equivalents from Maxim: MAX485, MAX487, MAX489, MAX490 (same low-power RS-485/RS-422 devices). Cross-vendor equivalents: TI SN65HVDx family (e.g., SN65HVD178/179) and Analog Devices ADM485/ADM248x (non-isolated RS-485/RS-422 transceivers).

Features

MAX488EPA is a 5V, low-power, half‑duplex RS-485/RS-422 transceiver. Key features:
- Single-supply 5V operation; 1/2 unit-load on the bus
- Driver enable (DE) and receiver enable (RE) with true 3‑state outputs
- Fail‑safe receiver: RO goes high with open, idle, or shorted inputs
- Low quiescent current for power‑sensitive applications
- Robust bus protection and wide common‑mode range; ESD/bus-pin protection
- Meets RS‑485/RS‑422 standards; suitable for multi‑drop networks
- Extended temperature range (industrial -40°C to +85°C)
- 8-pin Pb‑free package options (e.g., SOIC)

Pinout

- Pin count: 8 pins
- Function: Low-power, half-duplex RS-485/RS-422 transceiver. Provides DI (data in) and RO (data out), DE (driver enable) and /RE (receiver enable), differential bus pins A and B, plus Vcc and GND.

Manufacturer

The MAX488EPA is manufactured by Maxim Integrated Products. Maxim is a semiconductor company that designs and manufactures analog and mixed-signal integrated circuits. In 2021, Maxim was acquired by Analog Devices, Inc. (ADI), making Maxim a part of ADI, a multinational analog semiconductor company.

Application

MAX488EPA is a low-power, half-duplex RS-485/RS-422 transceiver. Common application areas include:
- Industrial automation (PLCs, remote I/O, motor drives) over RS-485 multipoint networks
- Building automation and energy metering (HVAC, lighting, smart meters)
- Data acquisition and instrumentation (remote sensors, data loggers)
- Telemetry and remote monitoring (SCADA, remote sites)
- General-purpose RS-485 communications (point-to-point or multipoint) in noisy, long-distance environments

Package

MAX488EPA is offered in an 8-pin plastic DIP (DIP-8) package. The “EPA” suffix denotes the PDIP package variant.
