MAX3078EEPA+

Overview

The MAX3078EEPA+ is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3.3V supply and supports data rates up to 16Mbps with unrestricted driver slew rates. The device features ±15kV ESD protection, fail-safe circuitry ensuring a logic-high receiver output when inputs are open or shorted, and hot-swap capability for safe bus insertion. It includes one driver and one receiver within an 8-pin Plastic DIP package.

Feature Summary

• Hot-swap input structure prevents false transitions during power-up or hot insertion
• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted
• Unrestricted driver slew rate enables high-speed transmission up to 16Mbps

Applications

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

Procurement Notes

Verify the specific suffix EEPA against official documentation to confirm the PDIP-8 package and -40°C to +85°C temperature range. Confirm RoHS compliance status through manufacturer datasheets. Ensure compatibility with existing board layouts requiring through-hole mounting for this specific transceiver variant.

Selection Notes

Select the MAX3078EEPA+ for applications requiring half-duplex communication at speeds up to 16Mbps. This component is suitable where unrestricted slew rates are necessary for high-speed data integrity. Verify that the system requires a 3.3V supply and benefits from integrated thermal shutdown and short-circuit protection mechanisms.

Part Context

This component belongs to the MAX3070E–MAX3079E family of +3.3V, ±15kV ESD-protected, fail-safe, hot-swap RS-485 transceivers. The MAX3078E specifically designates the half-duplex variant with unrestricted driver slew rates, distinguishing it from slew-rate-limited models in the same series.

Replacement Considerations

The ADM3078EARZ serves as a functional substitute within the same product family. Both devices offer identical electrical specifications, including 16Mbps data rates and half-duplex operation. Note that the ADM3078EARZ utilizes an SOIC-8 surface-mount package rather than the PDIP-8 through-hole package found in the MAX3078EEPA+.
