MAX3462CSA+

Drivers, Receivers, Transceivers Overview

The MAX3462CSA+ is a +5V, full-duplex RS-485/RS-422 transceiver in an 8-pin SO package. It features one differential driver and one receiver with true fail-safe circuitry guaranteeing a logic-high output when inputs are open or shorted. The device supports data rates up to 20Mbps with propagation delays under 20ns and skew less than 2ns. It operates from a +4.75V to +5.25V supply, drawing 2.5mA typically. The receiver input impedance is 1/4 unit load (48kΩ), allowing up to 128 transceivers on the bus. Driver outputs are current-limited and protected by thermal shutdown at +140°C.

Drivers, Receivers, Transceivers Feature Summary

• True fail-safe receiver ensures logic-high output during open or shorted input conditions
• Supports high-speed data transmission up to 20Mbps with low propagation delay
• Allows connection of up to 128 transceivers on a single bus line due to reduced input impedance
• Driver protection includes short-circuit current limiting and thermal shutdown

Drivers, Receivers, Transceivers Applications

• High-Speed RS-485 Communications
• High-Speed RS-422 Communications
• Industrial-Control Local Area Networks
• Profibus Applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the component matches the specific MAX3462CSA+ designation, ensuring it corresponds to the commercial temperature range (0°C to +70°C) and the 8-pin SO package format. Confirm that the suffix indicates standard specifications without additional specialized variants. Cross-reference the manufacturer's latest ordering information to ensure the part number remains active and available for procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex communication over RS-485 or RS-422 networks. It is suitable for systems needing to support a high node count, up to 128 devices, on a single bus. Ensure the design environment operates within the specified +5V supply range and that the thermal conditions remain within the commercial operating limits. This part is ideal for industrial control and Profibus environments requiring robust fault protection.

Drivers, Receivers, Transceivers Part Context

The MAX3462 is part of the MAX3460–MAX3464 family of high-speed differential bus transceivers designed for RS-485 and RS-422 communications. Unlike the half-duplex variants in the series, the MAX3462 provides full-duplex operation. It shares common features such as Profibus compatibility, fail-safe receivers, and thermal protection with its siblings, offering a compact 8-pin solution for bidirectional data transmission.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes within the same family include the MAX3462ESA (-40°C to +85°C) and MAX3462CPA/EPA (Plastic DIP packages). Other full-duplex options like the MAX3460 and MAX3461 offer additional features such as hot-swap capability and shutdown modes but require 14-pin packages.
