MAX3045BEUE/GG8

Overview

The MAX3045BEUE/GG8 is a quad RS-485/RS-422 transmitter from the MAX3040–MAX3045 family, designed for digital data transmission over twisted-pair balanced lines. It operates on a single +5V supply with a maximum data rate of 20Mbps. The device features ±10kV ESD protection (Human Body Model) and ±4kV Electrical Fast Transient/Burst immunity per IEC 1000-4-4. It includes hot-swap capability to prevent false transitions during power-up or insertion. The component is housed in a 16-pin TSSOP package and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Hot-swap capability eliminates false transitions on the data cable during power-up or hot insertion.
• Outputs protected against ±10kV electrostatic discharge using the Human Body Model.
• Withstands ±4kV Electrical Fast Transient/Burst stress per IEC 1000-4-4 standards.
• Pin-compatible with industry-standard 'SN75174 and 'DS26LS31C devices.

Applications

• Telecommunications Equipment
• Industrial Motor Control
• Transmitter for ESD-Sensitive Applications
• Hand-Held Equipment
• Industrial PLCs

Procurement Notes

Verify the specific suffix GG8 against official manufacturer documentation to confirm pinout or functional variations. Confirm RoHS compliance status and lead times through authorized distributors. Ensure the operating voltage matches the required +5V system rail. Check for availability of compatible receivers such as the MAX3093E or MAX3095 for optimal performance.

Selection Notes

Select this component when high-speed data rates up to 20Mbps are required for RS-485 or RS-422 networks. It is suitable for environments requiring robust ESD and transient immunity. Use this part if pin compatibility with legacy SN75174 designs is necessary while upgrading to lower power consumption. Ensure the application benefits from the integrated hot-swap feature for telecom or industrial backplanes.

Part Context

The MAX3045BEUE/GG8 belongs to the MAX3040–MAX3045 family of quad 5V transmitters. This series serves as a low-power upgrade to standard interface drivers. The family offers various data rate options, with the MAX3045B optimized for speeds up to 20Mbps. These devices are designed to work optimally with corresponding quad differential line receivers.

Replacement Considerations

Public confirmed substitute part numbers include MAX3045BCUE, MAX3045BESE, and MAX3045BEWE. These variants share identical electrical characteristics but differ in temperature range or package type. Verify pinout compatibility before substitution.
