MAX3032ECUE+T

Overview

The MAX3032ECUE+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 a guaranteed data rate of 20Mbps, featuring a maximum propagation delay of 16ns and part-to-part skew of less than 5ns. It includes ±15kV ESD protection on driver outputs and hot-swap functionality for safe insertion into live backplanes. 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

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

Applications

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

Procurement Notes

Verify the specific suffix 'C' indicates an operating temperature range of 0°C to +70°C. Confirm the 'UE' designation corresponds to the 16-pin TSSOP package type. Ensure the '+T' suffix matches the required reel packaging format for automated assembly processes.

Selection Notes

Select this model when dual independent enable controls are required for transmitter channels. Choose the EC variant for commercial temperature environments rather than industrial ranges. Verify that the 20Mbps speed rating aligns with system timing requirements compared to slew-rate-limited alternatives.

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 specifically provides dual enable functionality compatible with the SN75174 pinout configuration.

Replacement Considerations

Public confirmed substitute part numbers include MAX3032EEUE+T for extended temperature ranges.
