Overview
The MAX3293AUT+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 0.25Mbps and features slew-rate limiting to minimize EMI. The device draws 5mA of supply current when unloaded and reduces to 1µA in shutdown mode (DE = GND). It operates within 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 minimize electromagnetic interference and reduce reflections on improperly terminated cables
- Integrated hot-swap circuitry prevents false transitions during initialization or connection to live backplanes
- Built-in short-circuit current limiting and thermal-shutdown protection against excessive power dissipation
Applications
- RS-485/RS-422 Communications
- Automotive Systems
- Telecom Equipment
- Industrial Control
Procurement Notes
Verify the component authenticity by checking the top marking against the selector guide values ABNI or ABVH. Confirm the package type matches the specified 6-pin SOT23 configuration. Ensure the part number suffix corresponds to the lead-free and RoHS-compliant status indicated by the plus sign. Cross-reference the manufacturer details with Analog Devices Inc./Maxim Integrated specifications.
Selection Notes
Select this component specifically for applications requiring low-speed RS-485/RS-422 transmission at 250kbps where reduced electromagnetic interference is critical. The integrated slew-rate limiting makes it suitable for environments with improperly terminated cables. Verify that the system operates exclusively on a single +3.3V supply and requires the compact 6-pin SOT23 footprint.
Part Context
This device belongs to the MAX3293/MAX3294/MAX3295 family of low-power transmitters designed for RS-485/RS-422 communication. While the MAX3295 supports up to 20Mbps without slew-rate limiting, the MAX3293 variant is optimized for lower speeds with controlled edge rates. All members of this series share the same 6-pin SOT23 package and operate from a single +3.3V supply.
Replacement Considerations
MAX3294AUT+T offers higher speed at 2.5Mbps with similar slew-rate limiting. MAX3295AUT+T provides up to 20Mbps data rates but lacks slew-rate limiting.
