MAX3480AEPI

Drivers, Receivers, Transceivers Overview

The MAX3480AEPI is a half-duplex RS-422 and RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3V to 3.6V and supports data rates up to 250kbps. The device features 1 driver and 1 receiver, housed in a 28-PDIP package with through-hole mounting. It functions reliably across an extended temperature range of -40°C to +85°C. Key electrical specifications include a receiver hysteresis of 70mV and 15kV ESD protection.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 15kV electrostatic discharge (ESD) protection on all bus pins for enhanced robustness
• Compliant with RS-422 and RS-485 standards for reliable serial communication
• Low quiescent current architecture designed for power-efficient operation

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' indicates industrial temperature grade (-40°C to +85°C). Confirm the 'P' suffix corresponds to the PDIP-28 package type. Ensure RoHS compliance status matches project requirements. Check for lead-free manufacturing certifications if applicable.

Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing with RS-485 or RS-422 buses requiring high ESD immunity. The 28-pin DIP package suits prototyping or applications where surface mount space is not constrained. Verify that the 250kbps speed meets system timing requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX3480EA family of isolated RS-485/RS-422 transceivers. It shares functional similarities with the MAX3483 series but differs in pin count and isolation capabilities. The MAX3480AEPI represents the industrial-grade variant within the broader Maxim Integrated interface portfolio.

Drivers, Receivers, Transceivers Replacement Considerations

MAX3480BEPI+ is a compatible alternative within the same product family offering similar electrical characteristics and package options.
