MAX3086ECPD+

Overview

The MAX3086ECPD+ is a half-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a single 5V supply and supports data rates up to 10 Mb/s. The device features fail-safe circuitry, slew-rate limiting for EMI reduction, and high ESD protection. It is housed in a 14-pin PDIP package designed for through-hole mounting. Key electrical parameters include a minimum common-mode voltage range of -7V to +12V, a receiver input threshold of ±200mV, and an operating temperature range from 0°C to +70°C.

Feature Summary

• Fail-safe receiver design ensures logic high output when inputs are open or shorted
• Slew-rate limited drivers reduce electromagnetic interference during signal transitions
• High electrostatic discharge protection on bus pins prevents damage from transient events
• Low power consumption suitable for battery-operated systems

Applications

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

Procurement Notes

Verify the specific suffix 'ECPD+' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Check for obsolescence notices as older Maxim products may have limited availability. Ensure the procurement channel provides genuine components with traceable lot codes to avoid counterfeit risks in critical industrial applications.

Selection Notes

Select this component when a robust half-duplex interface is required for noisy environments. The fail-safe feature is critical for maintaining system stability during bus faults. Compare the 10Mb/s speed against lower-speed alternatives if bandwidth is not a constraint. Verify that the 14-pin DIP package fits the target PCB layout constraints compared to surface-mount options.

Part Context

This part belongs to the MAX308x family of RS-485/RS-422 transceivers. It shares functional similarities with the MAX3080 and MAX3082 but differs in package type and specific electrical tolerances. The 'E' grade indicates commercial temperature performance, while 'C' denotes the specific package variant within the Maxim product line hierarchy.

Replacement Considerations

Direct substitutes include the MAX3080ECPD+ and MAX3082ECPD+. Verify pin-to-pin compatibility and ensure the replacement meets the same 10Mb/s data rate requirement. Check if the alternative offers improved ESD ratings or extended temperature ranges if environmental conditions exceed commercial limits.
