MAX488ECPA+

Drivers, Receivers, Transceivers Overview

The MAX488ECPA+ is a low-power, full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply and features one driver and one receiver. The device supports data rates up to 250kbps with slew-rate-limited drivers to minimize EMI. It provides ±15kV ESD protection on all pins without latchup. The component includes fail-safe receiver inputs that guarantee a logic-high output when the input is open. It is housed in an 8-pin Plastic DIP package and operates within a temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver enable controls
• Slew-rate-limited drivers designed to reduce electromagnetic interference and signal reflections
• Integrated ±15kV electrostatic discharge protection on driver outputs and receiver inputs
• Fail-safe receiver circuitry ensures a high logic state during open-circuit conditions

Drivers, Receivers, Transceivers Applications

• Low-power RS-485 communication networks
• Low-power RS-422 communication networks
• EMI-sensitive industrial control applications
• Level translation between logic circuits and differential buses

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CPA+' against the manufacturer's current ordering guide to confirm the plastic DIP package and commercial temperature range specifications. Ensure the source document explicitly lists this part number variant as available or discontinued status matches project requirements. Cross-reference the datasheet revision date to validate electrical characteristics.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring full-duplex operation at speeds up to 250kbps with reduced EMI emissions. It is suitable for harsh environments due to robust ESD protection. Compare against half-duplex variants like the MAX485E if bidirectional single-wire communication suffices. Verify power consumption requirements align with the specified no-load supply current values.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX48xE family of low-power transceivers from Maxim Integrated. It shares pin compatibility with other members of the series but differs in duplex mode and data rate capabilities. The MAX488E specifically targets full-duplex applications, distinguishing it from the half-duplex MAX485E and MAX487E models within the same product line.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the MAX490E for equivalent full-duplex performance. Other family members like the MAX489E offer similar functionality in different packages. Verify pinout compatibility before substitution.
