Overview
The MAX3077EASA/GG8 is a full-duplex RS-422/RS-485 transceiver operating from a single 3.3V supply. It features one driver and one receiver with a maximum data rate of 16Mbps. The device provides ±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 to prevent false transitions during insertion. Supply current is typically 1.5mA. It operates within a temperature range of -40°C to +125°C and is housed in an 8-pin SO package.
Feature Summary
- Full-duplex communication architecture supporting simultaneous transmission and reception
- Integrated fail-safe mechanism that guarantees a high receiver output state under undefined bus conditions
- Hot-swap input structure on DE and RE pins to eliminate bus disturbances during power-up or board insertion
Applications
- Industrial control systems
- Telecommunications equipment
- Security systems
- Instrumentation
Procurement Notes
Verify the specific suffix GG8 against official manufacturer documentation to confirm pinout and package variations. Confirm availability status through authorized distributors as supply constraints may apply. Ensure compliance with RoHS directives by checking the specific ordering information for environmental certifications before procurement.
Selection Notes
Select this component for applications requiring full-duplex RS-422 or RS-485 communication at speeds up to 16Mbps. It is suitable for environments where hot-swap functionality and robust ESD protection are critical. Verify that the 3.3V supply voltage aligns with system requirements and that the 8-pin SO package fits the PCB layout constraints.
Part Context
This part belongs to the MAX3070E–MAX3079E family of +3.3V, ±15kV ESD-protected, fail-safe, hot-swap RS-485/RS-422 transceivers. The MAX3077E variant specifically supports full-duplex operation with unrestricted driver slew rates for high-speed data transmission.
Replacement Considerations
The MAX3076E and MAX3078E are direct functional substitutes within the same family, offering identical full-duplex performance and 16Mbps data rates. Verify package compatibility and temperature range specifications when substituting.
