MAX4998ETI+

Analog Switches - Special Purpose Overview

The MAX4998ETI+ is a dual-supply analog switch IC designed for DisplayPort applications. It integrates two-lane passive switches with a configuration of one SPDT and three DPDT channels. The device operates on a single supply voltage ranging from 3 V to 3.6 V. Key electrical parameters include a maximum on-resistance of 7 Ohms, a maximum turn-on time of 120 ns, and a maximum turn-off time of 50 ns. The maximum power supply current is 850 uA. It functions within an operating temperature range of -40°C to +85°C and is housed in a TQFN-28 package.

Analog Switches - Special Purpose Feature Summary

• Integrates two-lane passive switching capability specifically optimized for DisplayPort signal routing.
• Combines single-pole double-throw (SPDT) and triple double-pole double-throw (DPDT) configurations within a single channel architecture.

Analog Switches - Special Purpose Applications

• DisplayPort signal path switching
• Video source selection systems
• Multi-display management interfaces

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix and RoHS compliance status against the manufacturer's latest documentation before integration. Confirm that the TQFN-28 package dimensions match the target PCB footprint requirements. Ensure the single supply voltage range aligns with the system power design constraints.

Analog Switches - Special Purpose Selection Notes

Select this component when low on-resistance and fast switching speeds are required for DisplayPort lanes. Verify that the 3 V to 3.6 V supply range matches the system logic levels. Consider the thermal performance of the TQFN-28 package if multiple units are deployed in high-density designs.

Analog Switches - Special Purpose Part Context

This part belongs to the Maxim Integrated analog switch portfolio, focusing on video and display interface protection and routing. It serves as a specialized solution for managing high-bandwidth digital video signals where minimal signal distortion and fast transition times are critical for maintaining data integrity across DisplayPort connections.

Analog Switches - Special Purpose Replacement Considerations

Check for updated revisions or pin-compatible alternatives within the Analog Devices portfolio if availability becomes constrained. Verify functional equivalence regarding on-resistance and switching speed when considering cross-brand substitutes.
