MAX1480CCPI+

Drivers, Receivers, Transceivers Overview

The MAX1480CCPI+ 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 operates on a single +5V supply that powers both the logic and isolated sides. Key electrical parameters include an operating temperature range of 0°C to +70°C, isolation resistance of 10,000 MΩ, and isolation capacitance of 10 pF. The receiver input features fail-safe circuitry providing a known low output state when inputs are open.

Drivers, Receivers, Transceivers Feature Summary

• Integrated optical and magnetic isolation for complete signal and power barrier crossing
• Reduced-slew-rate driver design minimizes electromagnetic interference and cable reflections
• Single-supply operation simplifies power distribution across the isolation boundary
• Fail-safe receiver ensures defined logic states during open-circuit conditions

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 suffix 'C' indicates the commercial temperature grade (0°C to +70°C) and reduced slew rate capability compared to other variants in the family. Confirm the '+'' designation aligns with current RoHS compliance requirements. Ensure the 28-pin PDIP package matches the target PCB footprint constraints before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring galvanic isolation between control logic and high-noise industrial buses. The MAX1480C variant is appropriate where data rates do not exceed 250kbps but EMI reduction is critical. Compare against the MAX1480A if higher speeds up to 2.5Mbps are required, or the MAX1490 series for full-duplex requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1480/MAX1490 family of isolated interfaces. The MAX1480C specifically denotes the half-duplex, 250kbps version with slew-rate limiting. It shares the same physical package and pinout as the MAX1480B and MAX1480A, differing primarily in switching speed and thermal characteristics.
