MAX483ESA+T

Drivers, Receivers, Transceivers Overview

The MAX483ESA+T is a low-power, half-duplex RS-485 and RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates one driver and one receiver within an 8-pin SOIC package. The device operates on a single 5V supply (4.75V to 5.25V) and supports data rates up to 250kbps. Its driver features reduced slew rates to minimize electromagnetic interference (EMI) and reduce signal reflections. The component includes a low-current shutdown mode consuming only 0.1µA when both Receiver Enable (RE) is high and Driver Enable (DE) is low. It also incorporates thermal shutdown protection and fail-safe receiver circuitry.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers designed to minimize EMI and reduce reflections caused by improperly terminated cables.
• Low-power shutdown mode that reduces supply current consumption to typically 0.1µA when the driver and receiver are disabled.
• Fail-safe receiver input that guarantees a logic-high output if the differential input pins are left open or disconnected.

Drivers, Receivers, Transceivers Applications

• Industrial-control local area networks
• Transceivers for EMI-sensitive applications
• Level translators

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and temperature range. The 'E' suffix indicates an extended industrial temperature range of -40°C to +85°C, while the 'SA' suffix denotes an 8-pin SOIC package. Confirm RoHS compliance status through the manufacturer's certification documents before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for half-duplex RS-485 or RS-422 communication systems requiring low power consumption and EMI reduction. It is suitable for applications where data rates do not exceed 250kbps and bus line lengths may require tolerance for imperfect termination due to its slew-rate limitation. Ensure the system design accommodates the 5V supply voltage requirement.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX48x family of low-power transceivers from Maxim Integrated, now part of Analog Devices. The MAX483 specifically differentiates itself from other family members like the MAX481 or MAX485 by featuring slew-rate-limited drivers, which are optimized for reducing electromagnetic emissions in noisy environments compared to the faster, unrestricted drivers found in other variants.
