MAX1480BCPI-G10

Drivers, Receivers, Transceivers Overview

The MAX1480BCPI-G10 is a complete, electrically isolated RS-485/RS-422 data-communications interface hybrid microcircuit. It integrates transceivers, optocouplers, and a transformer within a standard 28-pin wide plastic DIP package. The device supports half-duplex communication with a maximum data rate of 250kbps. It features reduced-slew-rate drivers to minimize electromagnetic interference (EMI) and reduce reflections from improperly terminated cables. A single +5V supply on the logic side powers both sides of the interface. The unit typically withstands 1600V RMS isolation for one minute or 2000V RMS for one second.

Drivers, Receivers, Transceivers Feature Summary

• Integrated electrical isolation combining transceivers, optocouplers, and a transformer in a single package
• Reduced-slew-rate driver design minimizes EMI and cable reflection errors
• Single +5V logic-side power supply operation for both isolated and non-isolated sections
• Short-circuit current limiting and thermal shutdown protection for driver outputs

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 manufacturer documentation to confirm packaging configuration and lot traceability requirements. Ensure the component matches the required temperature range and isolation voltage specifications for the target application environment before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring half-duplex communication at speeds up to 250kbps where EMI reduction is critical. The MAX1480B variant is distinct from the MAX1480A, which supports higher speeds but lacks slew-rate limiting. Confirm that the 28-pin DIP footprint fits the board layout constraints and that the 1600V RMS isolation rating meets system safety standards.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1480 family of isolated RS-485/RS-422 interfaces manufactured by Analog Devices Inc./Maxim Integrated. The family includes variants like the MAX1480A and MAX1480C, which differ primarily in data rate capabilities and driver enable times. The MAX1480B specifically targets lower-speed, high-reliability industrial environments requiring minimized signal reflections.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1480ACPI+ serves as a parameter-equivalent alternative within the same product family, offering similar isolation and interface characteristics.
