MAX1482ESD+

Drivers, Receivers, Transceivers Overview

The MAX1482ESD+ is a low-power, full-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and supports data rates up to 250kbps. The device features slew-rate-limited drivers to minimize electromagnetic interference (EMI) and reduce reflections on improperly terminated cables. It draws only 20µA of operating current and includes a low-current shutdown mode consuming 0.1µA. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit. The part is housed in a 14-pin SO package and operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers minimize EMI and reduce reflections caused by improperly terminated cables
• Low power consumption with 20µA operating current and 0.1µA shutdown mode
• Fail-safe receiver input guarantees a logic-high output when the input is open circuit
• 1/8-unit-load input impedance allows up to 256 transceivers on the bus

Drivers, Receivers, Transceivers Applications

• Low-Power RS-485/RS-422 Networks
• Transceivers for EMI-Sensitive Applications
• Industrial-Control Local Area Networks
• Large 256-Node LANs

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Ensure the ordering suffix matches the required temperature range and package type. Confirm RoHS compliance status through the manufacturer's documentation before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication with low power consumption. The MAX1482ESD+ is suitable for environments where EMI reduction is critical due to its slew-rate-limited drivers. Consider the 1/8-unit-load capability for large network topologies requiring multiple nodes.

Drivers, Receivers, Transceivers Part Context

The MAX1482ESD+ belongs to the MAX1482/MAX1483 family of low-power RS-485/RS-422 transceivers. The 'E' suffix indicates an extended temperature range of -40°C to +85°C, while 'SD' denotes the 14-pin SO package. This variant is specifically designed for full-duplex operation, distinguishing it from the half-duplex MAX1483.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other MAX1482 variants with different packages or temperature ranges, such as MAX1482CPD or MAX1482EPD. Ensure compatibility with existing circuit designs regarding pinout and electrical characteristics.
