MAX3295AUT+CGK

Overview

The MAX3295AUT+CGK is a low-power, high-speed RS-485/RS-422 transmitter manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.3V supply and supports data rates up to 20Mbps with an output skew of less than 5ns and driver propagation delay below 25ns. The device draws 5mA in normal operation and 1µA in shutdown mode. It features hot-swap circuitry, short-circuit current limiting, and thermal shutdown protection. The component is specified over the automotive temperature range (-40°C to +125°C) and is housed in a 6-pin SOT23 package.

Feature Summary

• Space-saving 6-pin SOT23 package design
• Hot-swap inputs for telecom applications
• ESD protection rated at ±9kV Human Body Model
• Current limiting and thermal shutdown for driver-overload protection

Applications

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

Procurement Notes

Verify the specific suffix CGK against official documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the ordering code matches the AEC-Q100 qualified automotive variant if required for your application environment. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical specifications remain unchanged.

Selection Notes

Select this component when a single-ended input must be converted to a differential RS-485 or RS-422 signal at speeds up to 20Mbps. It is suitable for designs requiring minimal board space due to its compact SOT23-6 footprint. Consider this part for systems needing robust protection against bus faults and hot-plugging events without external components.

Part Context

This device belongs to the MAX329x family of transmitters designed for balanced communication standards. Unlike the MAX3293 and MAX3294, which are slew-rate limited to reduce EMI, the MAX3295 provides full-speed transmission capabilities. It shares the same physical package and basic protection features as its siblings but targets higher bandwidth requirements within the same power envelope.
