MAX1480ECCPI+

Drivers, Receivers, Transceivers Overview

The MAX1480ECCPI+ is a complete, electrically isolated RS-485/RS-422 data communications interface IC in a 28-pin wide plastic DIP package. It integrates transceivers, optocouplers, and a transformer to provide galvanic isolation between logic and signal sides using a single +5V supply. The device features slew-rate-limited drivers that minimize EMI and reduce reflections, supporting error-free data transmission at rates up to 160kbps. It offers ±15kV ESD protection on I/O pins without latchup, along with short-circuit current limiting and thermal shutdown for driver overload protection.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the slew-rate-limited variant with a maximum data rate of 160kbps, distinct from the high-speed 'A' variant. Confirm the 'P' suffix corresponds to the 28-pin Wide Plastic DIP package. Ensure the operating temperature range matches the application requirements for the commercial grade part. Cross-reference the manufacturer's latest datasheet for any updates to pin configurations or absolute maximum ratings before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring electrical isolation for RS-485 or RS-422 communication where electromagnetic interference is a concern. The reduced slew rate makes it suitable for long cables or improperly terminated lines to prevent signal reflections. It is appropriate for applications needing robust ESD protection and fail-safe receiver outputs. Consider the power consumption characteristics and the need for external pull-up resistors for the open-collector outputs when integrating into the circuit design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1480E/MAX1490E family of isolated data interfaces. The MAX1480 variants support half-duplex communication, whereas the MAX1490 counterparts provide full-duplex operation. Within the MAX1480 series, the 'A' suffix denotes high-speed capability up to 2.5Mbps, while the 'C' suffix specifies the slew-rate-limited version optimized for lower data rates up to 160kbps to enhance signal integrity in noisy environments.
