MAX3294AUT+

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 transmitter with a maximum data rate of 2.5Mbps and features slew-rate limiting to minimize EMI. The device draws 5mA of supply current when unloaded 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 for errorless data transmission
• Hot-swap inputs for telecom applications
• Current limiting and thermal shutdown for driver-overload protection

Applications

• RS-485/RS-422 Communications
• Clock Distribution
• Telecom Equipment
• Automotive
• Security Equipment

Procurement Notes

Verify the component against official Analog Devices documentation to confirm specifications and authenticity. Ensure the ordering suffix matches the required package and temperature grade. Cross-reference datasheet parameters with supplier catalogs to validate technical compliance before procurement.

Selection Notes

Select this component for designs requiring reduced electromagnetic interference due to its slew-rate limitation. It is suitable for systems needing hot-swap capability during board insertion. Verify that the 2.5Mbps data rate meets system requirements compared to faster or slower variants in the series.

Part Context

This part belongs to the MAX3293/MAX3294/MAX3295 family of low-power transmitters. These devices are designed for RS-485/RS-422 communication and operate from a single +3.3V power supply. They feature a space-saving 6-pin SOT23 package and are specified over the automotive temperature range.

Replacement Considerations

MAX3293AUT+T (250kbps) and MAX3295AUT+T (20Mbps) share the same package and pinout. Verify data rate requirements when substituting.
