MAX3032EESE+

Overview

The MAX3032EESE+ 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 typical operating voltage of 3.3V and a maximum static supply current of 100µA. The device supports a guaranteed data rate of 20Mbps, featuring a maximum propagation delay of 16ns and part-to-part skew less than 5ns. It provides ±15kV ESD protection on outputs and includes hot-swap functionality. The component is housed in a 16-pin Narrow SO package and functions within an extended temperature range of -40°C to +85°C.

Feature Summary

• Hot-swap capability prevents false transitions during power-up or insertion
• Dual enable inputs allow independent control of transmitter pairs
• Low-power design suitable for battery-operated systems
• Enhanced ESD protection on all driver outputs

Applications

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

Procurement Notes

Verify the ordering suffix EESE confirms the -40°C to +85°C temperature range and the 16-pin Narrow SO package. Confirm that the specific revision matches the required datasheet version. Ensure compatibility with existing board layouts due to industry-standard pinouts. Check for RoHS compliance status if environmental regulations apply to the assembly process.

Selection Notes

Select this model when dual independent enable controls are required for transmitter channels. Choose the EESE suffix for industrial temperature applications requiring operation down to -40°C. Verify that the 20Mbps data rate meets system timing requirements. Consider the narrow SO package dimensions for space-constrained PCB designs compared to standard SOIC options.

Part Context

This component 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 MAX3032E variant specifically offers dual enable functionality, distinguishing it from the global enable versions in the series.

Replacement Considerations

Direct replacements include other members of the MAX3030E–MAX3033E family with compatible packages. Verify pinout compatibility with legacy 26LS31 and SN75174 designs. Ensure thermal management requirements align with the specified junction temperature limits.
