MAX1480BEPI+

Drivers, Receivers, Transceivers Overview

The MAX1480BEPI+ is a complete, electrically isolated RS-485/RS-422 data interface solution housed in a 28-pin wide plastic DIP package. It integrates transceivers, optocouplers, and a transformer to provide isolation between the logic side and the signal path. The device operates on a single +5V supply and supports half-duplex communication with a maximum data rate of 250kbps. Key electrical parameters include an operating temperature range of -40°C to +85V, typical isolation withstand voltage of 1600VRMS (1 minute), and a shutdown supply current as low as 0.2µA.

Drivers, Receivers, Transceivers Feature Summary

• Integrated isolation barrier combining transceivers, optocouplers, and a transformer within a standard DIP package
• Reduced-slew-rate driver design minimizes electromagnetic interference and cable reflections for error-free transmission
• Single +5V power supply configuration powers both the logic and isolated sides of the interface
• Built-in thermal shutdown and short-circuit current limiting protect the driver outputs from damage

Drivers, Receivers, Transceivers Applications

• Isolated RS-485/RS-422 Data Interface
• Transceivers for EMI-Sensitive Applications
• Industrial-Control Local Area Networks
• Automatic Test Equipment
• HVAC/Building Control Networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact temperature grade and packaging specifications. Ensure that the component matches the required isolation ratings and duplex mode for the target application. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this model when half-duplex communication and reduced slew rates are required to minimize EMI. The BEPI+ variant is designated for the extended industrial temperature range (-40°C to +85°C). Compare against the MAX1480AEPI+ if higher data rates up to 2.5Mbps are needed, or the MAX1490 series if full-duplex operation is necessary for the system architecture.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1480 family of isolated RS-485/RS-422 interfaces. It shares the same functional block diagram and pinout structure as the MAX1480A and MAX1480C variants. The primary distinctions lie in the data rate capabilities and the specified operating temperature range defined by the ordering suffix.
