MAX22500EATB+

Drivers, Receivers, Transceivers Overview

The MAX22500EATB+ is a half-duplex RS-485/RS-422 transceiver optimized for high-speed communication over long cables. It supports data rates up to 100Mbps and operates on a 3V to 5.5V supply voltage with a logic supply down to 1.6V. The device features integrated preemphasis circuitry to reduce inter-symbol interference, fail-safe receivers, and hot-swap protection. It is housed in a 10-pin TDFN-EP package (3mm x 3mm) and functions within an ambient temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated preemphasis circuitry reduces inter-symbol interference caused by long cable attenuation.
• Hot-swap input circuitry prevents false driver transitions during power-up or board insertion.
• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted.
• Robust protection includes ±15kV ESD tolerance and ±15V common-mode range.

• Motion Control
• Encoder Interfaces
• Field Bus Networks
• Industrial Control Systems
• Backplane Busses

Drivers, Receivers, Transceivers Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required package type and RoHS compliance status. Cross-reference the datasheet revision history for any updates to absolute maximum ratings or thermal characteristics before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this model specifically for applications requiring preemphasis to extend reliable communication distances at high speeds. Verify that the system logic levels support the 1.6V minimum VL requirement. Confirm that the 10-pin TDFN-EP footprint fits the design constraints. Consider the MAX22501E variant if preemphasis functionality is not needed.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX22500E/MAX22501E family of high-speed RS-485/RS-422 transceivers. The MAX22500E series distinguishes itself through integrated preemphasis capabilities, whereas the MAX22501E lacks this feature. Both share similar protection mechanisms and operating voltage ranges but differ in package availability and specific interface requirements.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX22501EATB+ serves as a direct functional substitute if preemphasis is unnecessary. Other MAX22500 variants may be considered if different package options like μMAX are required, provided the pinout remains compatible.
