MAX3032ECUE+

Overview

The MAX3032ECUE+ is a quad RS-422 transmitter manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +3V to +3.6V and supports data rates up to 20Mbps. The device features ±15kV ESD protection on outputs, hot-swap capability, and low static current consumption below 100µA. It utilizes a 16-pin TSSOP package with an operating temperature range of 0°C to +70°C.

Feature Summary

• Hot-swap functionality prevents false transitions during power-up or insertion
• High ESD tolerance protects outputs against ±15kV human body model discharges
• Low static current consumption suitable for battery-powered applications

Applications

• Telecom Backplanes
• V.11/X.21 Interface
• Industrial PLCs
• Motor Control

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) rather than the extended range variant. Confirm the 'UE' designation corresponds to the 16-pin TSSOP package type required for your PCB layout. Ensure the '+T' or standard tape-and-reel packaging matches your assembly equipment specifications before finalizing orders.

Selection Notes

Select this component when driving parallel data streams due to its guaranteed 20Mbps rate and part-to-part skew under 5ns. Choose the ECUE+ variant specifically for commercial temperature environments requiring the TSSOP footprint. Verify that the dual enable pin configuration aligns with your control logic requirements compared to global enable alternatives.

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 26LS31 and SN75174 devices. The MAX3032E variant specifically provides dual enable inputs controlling transmitter pairs, distinguishing it from the single global enable architecture found in the MAX3030E and MAX3031E models.

Replacement Considerations

Direct pin-compatible replacements include the MAX3030ECUE+, MAX3031ECUE+, and MAX3033ECUE+. Note that the MAX3030E and MAX3031E utilize global enable pins, whereas the MAX3032E uses dual independent enable controls.
