MAX3295AUT-T

Overview

The MAX3295AUT-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 capable of data rates up to 20Mbps with an output skew of less than 5ns and guaranteed driver propagation delay below 25ns. The device draws 5mA of supply current when unloaded and 1µA in low-power shutdown mode (DE = GND). Hot-swap circuitry eliminates false transitions during initialization or connection to a live backplane. Short-circuit current limiting and thermal-shutdown circuitry protect the driver against excessive power dissipation. It is offered in a 6-pin SOT23 package and specified over the automotive temperature range.

Procurement Notes

Verify the component authenticity by checking the manufacturer's marking code ABNK or ABVJ on the top surface. Confirm the package type is SOT23-6 and the suffix T indicates tape and reel packaging. Ensure the part number matches the specific ordering information provided in the official datasheet to avoid counterfeit components.

Selection Notes

Select the MAX3295AUT-T when high-speed data transmission up to 20Mbps is required without slew-rate limiting. This component is suitable for applications needing hot-swap capability and robust protection features like thermal shutdown. Compare it with MAX3293 and MAX3294 if lower data rates and reduced EMI through slew-rate limiting are preferred instead.

Part Context

The MAX3295 is part of the MAX3293/MAX3294/MAX3295 family of low-power, high-speed transmitters for RS-485/RS-422 communication. All devices in this family operate from a single +3.3V power supply and contain one differential transmitter. They share similar features such as hot-swap capability, short-circuit current limiting, and thermal shutdown, but differ in maximum data rates and slew-rate limiting characteristics.
