MAX3084CPA

Overview

The MAX3084CPA is a low-power, half-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply with a specified data rate of 500 kbps and supports full-duplex communication capabilities within its family specifications. The device features fail-safe circuitry to ensure a high logic state at the receiver output when the inputs are open or disconnected. It is housed in an 8-pin PDIP package and is designed for operation over an extended temperature range from 0°C to +70°C.

Feature Summary

• Integrated fail-safe mechanism guarantees a defined high logic level at the receiver output during idle bus conditions or input disconnection.

Applications

• Industrial automation control systems requiring robust differential signaling
• Building automation networks utilizing RS-485 multi-drop configurations
• Process control instrumentation interfacing via standard serial protocols

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and specific manufacturing lot codes against current datasheet revisions. Ensure packaging integrity matches industrial handling requirements for through-hole mounting processes.

Selection Notes

Select this component for applications requiring reliable half-duplex communication on noisy industrial buses. Verify that the required data rate does not exceed 500 kbps and that the operating environment remains within the commercial temperature limits. Ensure power supply stability aligns with the specified +5V nominal voltage constraints.

Part Context

This part belongs to the MAX308x series of low-power RS-422/RS-485 transceivers. It shares functional similarities with other members like the MAX3080 and MAX3081 but differs in package type and specific electrical characteristics such as slew rate limitations and driver capability.

Replacement Considerations

Consider the MAX3084ECSA+ for surface-mount implementations offering identical electrical performance. Evaluate the MAX3080EESD+ if enhanced electrostatic discharge protection is required for sensitive environments.
