MAX3486EESA+T

Drivers, Receivers, Transceivers Overview

The MAX3486EESA+T is a half-duplex RS-485/RS-422 transceiver operating from a single +3.0V to +3.6V supply without requiring a charge pump. It supports data rates up to 2.5Mbps with partially slew-rate-limited drivers to minimize EMI and reflections. The device features ±15kV HBM, ±8kV IEC contact, and ±15kV IEC air-gap ESD protection on all I/O pins. It includes driver short-circuit current limiting and thermal shutdown for overload protection, alongside a receiver fail-safe feature that ensures a logic-high output when inputs are open.

Drivers, Receivers, Transceivers Feature Summary

• Partially slew-rate-limited drivers reduce electromagnetic interference and signal reflections caused by improperly terminated cables.
• Enhanced electrostatic discharge protection on transmitter outputs and receiver inputs withstands high static events across various testing models.
• Low-power shutdown mode significantly reduces supply current consumption when the driver and receiver are disabled.
• Receiver input fail-safe guarantees a logic-high output state if both differential inputs are left in an open circuit condition.

Drivers, Receivers, Transceivers Applications

• Telecommunications systems
• Industrial-control local area networks
• Integrated services digital networks
• Packet switching environments

Drivers, Receivers, Transceivers Procurement Notes
