MAX1482CSD

Drivers, Receivers, Transceivers Overview

The MAX1482CSD is a full-duplex RS-485/RS-422 transceiver in a 14-pin SO package. It operates from a single +5V supply (4.75V to 5.25V) with a typical operating current of 20µA and a shutdown current of 0.1µA. The device supports data rates up to 250kbps and features slew-rate-limited drivers for reduced EMI. It has a 96kΩ input impedance, allowing up to 256 units on the bus. Operating temperature range is 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate limited drivers minimize electromagnetic interference and signal reflections.
• Low-power operation with 20µA active current and 0.1µA shutdown mode.
• High-impedance receiver inputs support up to 256 nodes on the communication bus.
• Integrated thermal shutdown and short-circuit current limiting protect against driver overload.

Drivers, Receivers, Transceivers Applications

• Low-power RS-485 and RS-422 communication networks
• Industrial control local area networks
• EMI-sensitive applications requiring reduced signal reflections

Drivers, Receivers, Transceivers Procurement Notes

Verify the component matches the specific C suffix designation for the commercial temperature range of 0°C to +70°C. Confirm the S suffix indicates the 14-pin Small Outline package. Ensure authenticity through authorized channels as counterfeit components may affect reliability.

Drivers, Receivers, Transceivers Selection Notes

Select this part for full-duplex RS-485 or RS-422 applications requiring low power consumption. The MAX1483 variant should be chosen if half-duplex operation is sufficient. Verify that the system voltage aligns with the specified 5V supply requirement.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1482/MAX1483 family of low-power transceivers manufactured by Analog Devices Inc./Maxim Integrated. The MAX1482 provides full-duplex capability, while the MAX1483 offers half-duplex functionality within the same low-power architecture.

Drivers, Receivers, Transceivers Replacement Considerations

MAX1483CSD is the half-duplex equivalent within the same series. Other RS-485 transceivers may require circuit modifications due to differences in unit load specifications or supply voltage ranges.

Drivers, Receivers, Transceivers FAQ

What is the difference between the MAX1482 and MAX1483?

The MAX1482 is a full-duplex transceiver, whereas the MAX1483 is a half-duplex transceiver. Both share similar electrical characteristics and pinouts.

How does the device handle an open receiver input?

The receiver includes a fail-safe feature that guarantees a logic-high output if the A and B inputs are left open circuit.

What protection mechanisms are included for the driver outputs?

The drivers feature short-circuit current limiting and thermal shutdown circuitry that forces outputs to a high-impedance state during excessive power dissipation.
