MAX3077EESA+T

Overview

The MAX3077EESA+T is a full-duplex RS-485 transceiver operating from a single +3.3V supply. It features one driver and one receiver with data rates up to 16Mbps. The device includes ±15kV ESD protection on I/O pins, fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and hot-swap capability for the DE and RE pins. Supply current is 800μA in unloaded conditions. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package.

Feature Summary

• Full-duplex communication architecture supporting high-speed data transmission up to 16Mbps without slew-rate limiting.
• Integrated fail-safe receiver guarantees a logic-high output state during bus idle, open-circuit, or short-circuit conditions.
• Hot-swap input structure on Driver Enable (DE) and Receiver Enable (RE) pins prevents false transitions during board insertion or power-up sequences.

Applications

• Industrial control systems
• Telecommunications equipment
• Security systems

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to project requirements. Ensure proper handling procedures are followed due to electrostatic sensitivity.

Selection Notes

Select this model for applications requiring full-duplex RS-485 connectivity at speeds up to 16Mbps. It is suitable where hot-swap functionality and robust ESD protection are critical design constraints. Verify that the 800μA supply current meets system power budget requirements.

Part Context

This component belongs to the MAX3070E–MAX3079E family of +3.3V RS-485 transceivers manufactured by Analog Devices / Maxim Integrated. The family differentiates models primarily by duplex mode and slew-rate limitations, with the MAX3077E specifically designated for full-duplex operation at maximum speed.

Replacement Considerations

The MAX3076E and MAX3078E are direct functional substitutes within the same series offering identical electrical characteristics and pinouts.
