MAX4917BELT+T

Current Regulation/Management Overview

The MAX4917BELT+T is a dual, low-power RS-485/RS-422 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates from a single 3.0V to 5.5V supply and supports data rates up to 20Mbps. The device features fail-safe receivers that ensure a high logic output when inputs are open or shorted. It includes thermal shutdown protection and is housed in an 8-pin TDFN package.

Current Regulation/Management Feature Summary

• Supports RS-485 and RS-422 communication standards with high-speed data transmission capabilities.
• Incorporates fail-safe receiver circuitry to maintain a defined high state during input disconnection.
• Provides thermal shutdown protection to safeguard the device under excessive heat conditions.

Current Regulation/Management Applications

• Industrial automation control systems
• Building automation networks
• Metering infrastructure

Current Regulation/Management Procurement Notes

Verify the specific suffix BELT corresponds to the tape-and-reel packaging configuration. Confirm the manufacturer designation as Analog Devices Inc., formerly Maxim Integrated, for accurate sourcing. Ensure the component meets RoHS compliance standards indicated by the + symbol in the part number.

Current Regulation/Management Selection Notes

Select this component for applications requiring dual transceivers in a compact footprint. Consider its low power consumption and wide operating voltage range suitable for battery-powered devices. Evaluate the need for fail-safe features in noisy industrial environments before finalizing the design.

Current Regulation/Management Part Context

This part belongs to the MAX491x family of half-duplex and full-duplex transceivers designed for robust serial communication. It complements other high-speed interface solutions by offering integrated protection and low standby current, fitting into broader system designs requiring reliable data exchange over twisted pair lines.

Current Regulation/Management Replacement Considerations

Check for direct pin-compatible alternatives within the MAX485 or MAX308x families if supply constraints exist. Verify that any substitute maintains the same 20Mbps speed rating and 3.0V-5.5V operating voltage range to ensure circuit compatibility without redesign.

Current Regulation/Management FAQ
