MAX3083CPD+

Overview

The MAX3083CPD+ is a full-duplex RS-422/RS-485 transceiver in a 14-pin PDIP package. It supports data rates up to 10 Mbps with slew-rate limiting to reduce EMI. The device features fail-safe circuitry ensuring a high logic state when inputs are open. It operates on a single 5 V supply and includes 15 kV ESD protection on all bus pins.

Feature Summary

• Fail-safe receiver design ensures a defined high logic state for differential inputs when the bus is idle or disconnected.
• Slew-rate limited drivers minimize electromagnetic interference (EMI) during signal transitions.
• Integrated electrostatic discharge (ESD) protection rated at 15 kV on all bus interface pins.

Applications

• Industrial automation control networks
• Building automation systems
• Multi-drop communication buses

Procurement Notes

Verify the specific suffix 'CPD+' indicates the lead-frame material and environmental compliance status as defined by Analog Devices. Confirm that the PDIP-14 package matches the target PCB footprint requirements. Ensure the component meets RoHS directives if required by the final assembly specifications.

Selection Notes

Select this part for applications requiring full-duplex communication over twisted-pair lines. It is suitable where EMI reduction is critical due to slew-rate limiting. Choose this model over half-duplex variants when simultaneous transmit and receive capabilities are necessary for the system architecture.

Part Context

This component belongs to the MAX308x family of high-speed serial interface transceivers. It shares functional similarities with the MAX3080 and MAX3081 but differs in package type and pinout configuration. The series is designed for robust operation in electrically noisy industrial environments.

Replacement Considerations

The MAX3083EEDT+ serves as a surface-mount equivalent within the same product family. Verify that the SOIC-14 package dimensions are compatible with the existing board layout before substitution.

FAQ
