MAX3032EESE+T

Overview

The MAX3032EESE+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 a typical static current of 100µA. The device guarantees a maximum data rate of 20Mbps and features ±15kV ESD protection on driver outputs. It utilizes a 16-pin Narrow SO package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Guaranteed 20Mbps high-speed data transmission capability
• Integrated hot-swap functionality to prevent false transitions during power-up
• Enhanced ±15kV electrostatic discharge protection on all driver outputs
• Low-power design suitable for battery-operated applications

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the EE designation corresponds to the extended industrial temperature range of -40°C to +85°C. Ensure the SE package variant matches the required narrow SO footprint for the target PCB layout.

Selection Notes

Select this model for applications requiring four independent RS-422 drivers without integrated receivers. Choose the MAX3032 variant specifically for dual enable pin configurations controlling channels 1/2 and 3/4 separately. Opt for this part over slew-rate-limited versions when maximum bandwidth is prioritized over EMI reduction.

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 inputs, distinguishing it from the global enable configuration found in the MAX3030E/MAX3031E variants.

Replacement Considerations

Direct functional replacements within the same family include the MAX3032ECSE+ (commercial temperature) or MAX3032EEUE+ (TSSOP package). Verify thermal requirements before substituting commercial grade parts.
