MAX3032EEUE+T

Overview

The MAX3032EEUE+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 functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Hot-swap capability prevents false transitions on the data cable during power-up or hot insertion
• Outputs feature enhanced electrostatic discharge (ESD) protection rated at ±15kV using the Human Body Model
• Low-power design suitable for battery-powered applications with minimal static current draw
• Dual enable inputs allow independent control of transmitter channels 1/2 and 3/4

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required specifications, as variations exist between tape-and-reel, cut-tape, and tube packaging formats. Confirm the specific temperature grade and package type align with the project requirements before finalizing the purchase order.

Selection Notes

Select this component when high-speed differential signaling up to 20Mbps is required alongside low standby power consumption. Ensure the application benefits from the dual-enable architecture for channel-specific control rather than global transmitter management.

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 MAX3032E variant specifically offers dual enable inputs compatible with the SN75174 pinout.

Replacement Considerations

The MAX3030EEUE+T and MAX3031EEUE+T are pin-compatible alternatives within the same family. Verify if global enable functionality is acceptable instead of the dual-enable configuration provided by the MAX3032E.
