MAX3486ESA

Drivers, Receivers, Transceivers Overview

The MAX3486ESA is a half-duplex RS-422/RS-485 transceiver operating from a single +3.0V to +3.6V supply. It supports data rates up to 2.5Mbps with partially slew-rate-limited drivers. The device features ±15kV ESD protection (Human Body Model), a -7V to +12V common-mode range, and a low-power shutdown mode drawing 2nA. It operates within the -40°C to +85°C temperature range in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±15kV ESD protection on all I/O pins
• Low-power shutdown mode for minimal current consumption
• Partially slew-rate-limited driver output
• Fail-safe receiver input logic

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm the operational temperature range and RoHS compliance status. Ensure the ordering code matches the required package style and voltage specifications before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for half-duplex RS-485 or RS-422 communication requiring moderate speeds up to 2.5Mbps. It is suitable for environments needing robust ESD protection and low standby power via the shutdown feature. Verify compatibility with +5V logic levels if interfacing with higher voltage controllers.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX3483E family of 3.3V transceivers. It shares the industry-standard 75176 pinout with other members like the MAX3483E and MAX3485E. The family differentiates based on data rate capabilities and duplex modes, with this model specifically optimized for balanced performance between speed and noise immunity.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes within the same family include the MAX3483ESA and MAX3485ESA. These parts share identical pinouts and packaging but differ in maximum data rates and driver slew-rate characteristics. Confirm that the alternative meets the specific timing requirements of the application.

Drivers, Receivers, Transceivers FAQ

How is the low-power shutdown mode activated?

Shutdown is initiated by driving the Receiver Enable (RE) pin high and the Driver Enable (DE) pin low simultaneously.

What is the fail-safe feature of the receiver?

The receiver guarantees a logic-high output state if both differential inputs are left open-circuited.

Does this device support full-duplex communication?

No, the MAX3486E is designed exclusively for half-duplex communication.
