MAX1483EPA+

Drivers, Receivers, Transceivers Overview

The MAX1483EPA+ is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply (4.75V to 5.25V) and supports data rates up to 250kbps. The device features low power consumption with 20µA operating current and 0.1µA shutdown current. It includes slew-rate-limited drivers, thermal shutdown, short-circuit protection, and a fail-safe receiver. The component utilizes an 8-pin PDIP package and functions within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers minimize electromagnetic interference and reduce signal reflections on improperly terminated cables.
• Low-power architecture provides 20µA operating current and a dedicated 0.1µA shutdown mode for energy conservation.
• Integrated driver protection mechanisms include foldback current limiting and thermal shutdown circuitry to prevent damage during faults.

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 against official manufacturer documentation to confirm the exact package type and temperature rating. Ensure that any additional characters in the part number do not indicate variations in functionality or electrical specifications beyond those defined in the standard datasheet.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high node density due to its 1/8-unit-load input impedance, which supports up to 256 devices on a single bus. Choose this model over full-duplex variants when bidirectional communication on a shared line is sufficient. Verify that the system voltage aligns with the specified single +5V supply requirement.

Drivers, Receivers, Transceivers Part Context

The MAX1483EPA+ belongs to the MAX1482/MAX1483 family of low-power transceivers designed for RS-485 and RS-422 communications. While the MAX1482 provides full-duplex operation, the MAX1483 is configured specifically for half-duplex applications. Both share identical low-power characteristics and protection features.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX1483CPA serves as a commercial grade alternative within the same family, offering identical electrical performance but rated for a 0°C to +70°C operating temperature range instead of the industrial -40°C to +85°C range found in the MAX1483EPA+.
