MAX3076EESD+T

Overview

The MAX3076EESD+T is a full-duplex RS-485 transceiver operating from a single +3.3V supply. It features one driver and one receiver with no slew-rate limiting, supporting data rates up to 16Mbps. The device includes ±15kV ESD protection on I/O pins, true fail-safe circuitry, and hot-swap capability on DE and RE inputs. Supply current is 1.5mA typical, with a shutdown mode drawing 10µA maximum. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Hot-swap input structure prevents false transitions during power-up or board insertion
• True fail-safe receiver guarantees logic-high output when inputs are open or shorted
• Unlimited driver slew rate enables high-speed communication up to 16Mbps

Applications

• Industrial Control Systems
• Telecommunications Equipment
• Security Systems
• Instrumentation

Procurement Notes

Verify the specific suffix 'ESD+T' against the manufacturer's official documentation to confirm tape-and-reel packaging and lead-free status. Confirm that the 'E' designation corresponds to the industrial temperature range of -40°C to +85°C for the intended application environment.

Selection Notes

Select this component for applications requiring full-duplex RS-485 communication at speeds up to 16Mbps. Ensure the design accommodates the lack of slew-rate limiting by managing cable termination properly to minimize EMI. Verify that the 3.3V supply voltage aligns with the system power architecture.

Part Context

This part belongs to the MAX3070E–MAX3079E family of 3.3V RS-485 transceivers. Unlike the MAX3073E or MAX3075E which limit slew rates for lower speeds, the MAX3076E provides unrestricted drive speed. It shares the same fail-safe and hot-swap features as other members in the series but is optimized for higher bandwidth requirements.

Replacement Considerations

The MAX3076EAPD+ serves as a pin-compatible alternative in a 14-pin DIP package. Other family members like the MAX3073E offer similar functionality but with reduced maximum data rates due to internal slew-rate limiting.
