MAX3030ECUE+T

Overview

The MAX3030ECUE+T is a quad RS-422 transmitter manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3V to +3.6V supply with a maximum static current consumption of less than 100µA. The device supports data rates up to 20Mbps, featuring a maximum propagation delay of 16ns and part-to-part skew under 5ns. It provides ±15kV ESD protection on driver outputs and includes hot-swap functionality to prevent false transitions during power-up. The component is housed in a 16-pin TSSOP package and complies with TIA/EIA-422-B and ITU-T V.11 standards.

Feature Summary

• Complies with TIA/EIA-422-B (RS-422) and ITU-T V.11 recommendations
• Provides ±15kV ESD protection on all transmitter outputs
• Features hot-swap capability to eliminate false transitions during power-up or insertion
• Offers low-power design with static current consumption below 100µA

Applications

• Telecom backplanes
• V.11/X.21 interface systems
• Industrial PLCs
• Motor control applications

Procurement Notes

Verify the specific suffix 'ECUE' corresponds to the required operating temperature range of 0°C to +70°C and the 16-pin TSSOP package configuration. Confirm that the '+T' designation indicates tape-and-reel packaging if reel handling is necessary for assembly. Ensure compatibility with existing board layouts designed for industry-standard pinouts like the 26LS31.

Selection Notes

Select this component when high-speed data transmission up to 20Mbps is required over twisted-pair balanced lines. It is suitable for battery-powered applications due to its low static current consumption. Choose this model over slew-rate-limited variants when minimal propagation delay and tight skew specifications are critical for parallel data driving.

Part Context

This device belongs to the MAX3030E–MAX3033E family of quad RS-422 transmitters. It serves as a low-power, ESD-protected upgrade to industry-standard devices such as the 26LS31 and SN75174. The family offers both 20Mbps and 2Mbps baud rate options, with the MAX3030E specifically optimized for higher speed performance.

Replacement Considerations

Public confirmed substitute part numbers include MAX3030ECSE+T (SOIC package), MAX3030EEUE+T (Extended temp/TSSOP), and MAX3030EESE+T (Extended temp/SOIC). These parts share identical electrical characteristics but differ in package type or operating temperature range.
