MAX1482CSD-T

Drivers, Receivers, Transceivers Overview

The MAX1482CSD-T is a low-power 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 EMI and reduce reflections. It draws only 20µA of operating current and enters a shutdown mode consuming 0.1µA. The receiver input has a fail-safe feature guaranteeing a logic-high output if the input is open circuit. It offers short-circuit current limiting and thermal shutdown protection. The part is housed in a 14-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate limited drivers for reduced EMI and reflections
• Low power consumption with 20µA operating current and 0.1µA shutdown mode
• Fail-safe receiver input guarantees logic-high output when open
• Short-circuit current limiting and thermal shutdown protection

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 specific ordering suffix 'T' indicates tape-and-reel packaging, as standard datasheets list 'MAX1482CSD' without the suffix. Confirm the manufacturer's official documentation regarding the exact reel specifications and quantity per reel associated with this suffix variant before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the MAX1482CSD-T for full-duplex RS-485 applications requiring low power consumption and high noise immunity. Ensure the system design accommodates the 14-pin SOIC package dimensions. Verify that the required data rate does not exceed 250kbps and that the operating temperature range aligns with the C-grade specification limits.

Drivers, Receivers, Transceivers Part Context

The MAX1482CSD belongs to the MAX1482/MAX1483 family of low-power transceivers designed for RS-485 and RS-422 communication. The MAX1482 variant provides full-duplex operation, distinguishing it from the half-duplex MAX1483. Both share identical low-power characteristics and 1/8-unit-load input impedance, allowing up to 256 transceivers on a single bus.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1483 serves as a functional alternative for half-duplex applications within the same family.
