MAX3483AEASA+T

Drivers, Receivers, Transceivers Overview

The MAX3483AEASA+T is a half-duplex RS-485/RS-422 transceiver operating from a single 3.3V supply (3.0V to 3.6V). It supports data rates up to 250kbps with slew-rate limiting. The device features ±20kV HBM ESD protection on driver outputs and receiver inputs, compliant with IEC 61000-4-2 standards. It includes a fail-safe receiver that ensures a logic-high output when inputs are open or shorted. Supply current is typically 1.9mA in active mode and less than 10µA in shutdown mode. The component operates within an extended temperature range of -40°C to +125°C and is housed in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated hot-swap capability prevents false transitions during power-up or board insertion by holding enable inputs in safe states until VCC stabilizes.
• True fail-safe receiver design guarantees a logic-high output state when differential inputs are disconnected, shorted, or connected to a terminated bus with all drivers disabled.
• Enhanced electrostatic discharge protection on A, B, Y, and Z pins withstands ±20kV Human Body Model and ±15kV Air-Gap discharges without damage.
• Short-circuit protected driver outputs provide continuous protection against faults, supported by thermal shutdown circuitry that activates at elevated junction temperatures.

Drivers, Receivers, Transceivers Applications

• Industrial-control local area networks
• Transceivers for EMI-sensitive applications
• Telecommunications systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ASA+T' corresponds to the tape-and-reel packaging format and lead-free composition as defined in the manufacturer's ordering guide. Confirm the component meets RoHS directives and REACH requirements for the intended market. Ensure the source documentation matches the exact part number to validate the 8-pin SO package type and the specified electrical characteristics for the AE family variant.

Drivers, Receivers, Transceivers Selection Notes

Select this component for half-duplex RS-485/RS-422 communication links requiring robust ESD immunity and operation in noisy industrial environments. The 1-unit load receiver impedance limits the bus to 32 nodes; use quarter-load variants if higher node counts are required. Verify that the 250kbps data rate aligns with system timing requirements, as faster speeds are available in other family members like the MAX3485AE.

Drivers, Receivers, Transceivers Part Context

The MAX3483AE belongs to the MAX3483AE/MAX3485AE/MAX3488AE/MAX3490AE/MAX3491AE family of +3.3V-powered transceivers. While the MAX3483AE provides 250kbps performance with 1-unit load impedance, sibling parts offer higher speeds or increased bus capacity. All devices share common features such as slew-rate limiting and integrated ESD protection, designed for reliable bidirectional data communications on multipoint bus transmission lines.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX3483EESA+T is a related half-duplex variant within the same family but offers different speed and impedance specifications. Verify functional compatibility regarding data rate and node capacity before substitution. Other family members like the MAX3485AE provide higher data rates but may require different system timing considerations.
