MAX485ESA SMD IC Maxim SOIC8 MAX485ESA+T

Product Overview:

A low-power, slew-rate-limited integrated circuit designed for RS-485 and RS-422 communication applications. These transceivers are optimized for industrial-control local area networks, EMI-sensitive applications, and level translation, featuring short-circuit current limiting and thermal shutdown protection.

Core Specifications:

Manufacturer: Maxim Integrated

Package Type: 8-pin (available in µMAX, SO, and Plastic DIP)

Function: Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceiver

Input Channels: 1 driver and 1 receiver (half or full-duplex depending on the specific model)

Control Interface: TTL/CMOS Logic Interface (Driver/Receiver enable pins)

Features:

• Single 5V supply operation

• Reduced slew-rate drivers available on specific models (e.g., MAX483, MAX487, MAX488, MAX489) to minimize EMI

• Data rates up to 2.5 Mbps (non-slew-rate-limited) or 250 kbps (slew-rate-limited)

• Low-current shutdown mode available on select models (e.g., MAX481, MAX483, MAX487)

• Fail-safe receiver input guarantees logic-high output for open-circuit inputs

• Thermal shutdown circuitry protects against excessive power dissipation
