MAX3032ECSE+T

Overview

The MAX3032ECSE+T is a quad RS-422 transmitter from the MAX3030E–MAX3033E family, designed for digital data transmission over twisted-pair balanced lines. It operates on a single +3V to +3.6V supply with low static current consumption of less than 100µA. The device supports a guaranteed maximum data rate of 20Mbps and features a maximum propagation delay of 16ns with part-to-part skew under 5ns. It includes ±15kV ESD protection on outputs and hot-swap capability to prevent false transitions during power-up. The component is housed in a 16-pin Narrow SO package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Complies with TIA/EIA-422-B (RS-422) and ITU-T V.11 standards
• Provides ±15kV ESD protection on driver outputs using the Human Body Model
• Features hot-swap functionality to eliminate false transitions during board insertion or power-up
• Guarantees a 20Mbps data rate with low propagation delay suitable for parallel data driving

Applications

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

Procurement Notes

Verify the specific suffix 'CSE' confirms the commercial temperature range (0°C to +70°C) and the Narrow SO-16 package type. Ensure the '+T' designation aligns with the required reel packaging format. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility with legacy 26LS31 or SN75174 equivalents if replacing existing designs.

Selection Notes

Select this model when a 20Mbps baud rate is required alongside low static power consumption. The dual-enable pin configuration distinguishes it from the MAX3030E/MAX3031E variants, which use global enable signals. Verify that the narrow SO-16 package dimensions fit the PCB layout constraints compared to the TSSOP alternative.

Part Context

This component belongs to the MAX3030E–MAX3033E family of low-power, ESD-protected quad RS-422 transmitters. It serves as a modern upgrade to industry-standard devices like the 26LS31 and SN75174. The family offers both 2Mbps slew-rate-limited and 20Mbps high-speed options across various package types and temperature grades.

Replacement Considerations

Direct pin-compatible replacements include MAX3032EESE+T for extended temperature ranges and MAX3032ECUE+T for TSSOP packaging. For legacy integration, verify electrical compatibility with 26LS31 and SN75174 drivers.
