MAX3294AUT+T

Overview

The MAX3294AUT+T is a low-power, high-speed transmitter for RS-485/RS-422 communication operating from a single +3.3V supply. It contains one differential driver with a maximum data rate of 2.5Mbps and features slew-rate limiting to minimize EMI. The device draws 5mA in normal operation and 1µA in shutdown mode. It operates over an automotive temperature range of -40°C to +125°C and is housed in a 6-pin SOT23 package.

Feature Summary

• Slew-rate limited output to reduce electromagnetic interference and reflections
• Integrated hot-swap circuitry prevents false transitions during board insertion
• Short-circuit current limiting and thermal-shutdown protection

Applications

• RS-485/RS-422 Communications
• Automotive Systems
• Industrial Control

Procurement Notes

Verify the component against official Analog Devices documentation to confirm authenticity. Ensure the ordering suffix matches the required specifications. Check for RoHS compliance status as indicated by the plus sign in the part number. Confirm the package type and temperature rating align with design requirements before procurement.

Selection Notes

Select this component when a compact RS-485/RS-422 transmitter is needed with reduced EMI characteristics. The MAX3294 offers a balanced speed between the MAX3293 and MAX3295. Verify that the 2.5Mbps data rate meets system requirements. Ensure the application benefits from the integrated hot-swap feature for backplane connections.

Part Context

This device belongs to the MAX3293/MAX3294/MAX3295 family of low-power transmitters. All members share the same 6-pin SOT23 package and operate from a +3.3V supply. The primary distinction lies in their data rates and slew-rate limiting capabilities, allowing designers to choose based on speed and EMI constraints.

Replacement Considerations

MAX3293AUT+T and MAX3295AUT+T are pin-compatible alternatives within the same family.
