MAX3030EESE+

Overview

The MAX3030EESE+ 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 and features a maximum propagation delay of 16ns with part-to-part skew under 5ns. It includes ±15kV ESD protection on driver outputs, hot-swap functionality, and thermal shutdown. The component is housed in a 16-pin Narrow SO package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Complies with TIA/EIA-422-B (RS-422) and ITU-T V.11 standards for digital data transmission over twisted-pair balanced lines.
• Provides enhanced electrostatic discharge protection rated at ±15kV on all transmitter outputs using the Human Body Model.
• Incorporates hot-swap capability to prevent false transitions on the data cable during power-up or hot insertion events.
• Features low-static current consumption suitable for battery-powered applications and includes thermal shutdown protection.

Applications

• Telecom backplanes
• V.11/X.21 interface circuits
• Industrial programmable logic controllers (PLCs)
• Motor control systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package type and temperature range. Ensure the component source is authorized to guarantee authenticity and traceability. Check for RoHS compliance status as indicated in the manufacturer's specifications before finalizing procurement orders.

Selection Notes

Select this component when designing high-speed serial communication links requiring RS-422 compliance. It is appropriate for systems needing multiple differential drivers with low standby power. Consider the 16-pin narrow SO package constraints and verify that the application environment stays within the specified -40°C to +85°C operational limits.

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 like the 26LS31 and SN75174. The family offers pin-compatible options in both 16-pin TSSOP and Narrow SO packages to facilitate design flexibility.

Replacement Considerations

Direct replacements include other members of the MAX3030E–MAX3033E family such as the MAX3032EESE+, which shares identical electrical characteristics but utilizes dual enable inputs instead of global enable controls.
