MAX4983EELB+T

Analog Switches - Special Purpose Overview

The MAX4983EELB+T is a USB switch IC designed for high-speed USB 2.0 applications, featuring a single DPDT configuration within a compact 10-µDFN package. It operates on a single supply voltage ranging from 2.8 V to 5.5 V with a typical quiescent current of 3 µA. The device supports data rates up to 480 Mbps, offering a bandwidth of 950 MHz and an on-resistance maximum of 10 Ohms. Switching times are characterized by a maximum turn-on time of 100 µs and a maximum turn-off time of 5 µs. It functions reliably across an extended temperature range from -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Integrated ±15kV human body model ESD protection on common terminals
• Supports USB 2.0 high-speed data transmission standards
• Ultra-low power consumption suitable for battery-operated devices

Analog Switches - Special Purpose Applications

• USB hub implementations requiring port switching
• Laptop docking stations for peripheral management
• Portable electronic devices with limited power budgets

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'ELB' against official Analog Devices documentation to confirm pinout and thermal pad configurations. Ensure compatibility with existing PCB footprints, as package dimensions are critical for surface-mount assembly. Cross-reference RoHS compliance status directly with manufacturer certificates prior to integration into regulated products.

Analog Switches - Special Purpose Selection Notes

Select this component when high-speed signal integrity is required alongside robust electrostatic discharge protection. The low on-resistance ensures minimal signal attenuation for USB 2.0 protocols. Consider the small form factor if board space is constrained in portable designs. Verify that the operating voltage range aligns with the system's power rail specifications.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4983E series of USB switches, which are optimized for high-speed data lines. The family typically includes variants with different packaging options such as QFN or µDFN. These components are engineered to manage USB connectivity while maintaining signal quality and protecting downstream circuitry from electrical stress events common in consumer electronics.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include other Maxim Integrated USB switches like the MAX4984E series, which offers similar functionality but may differ in channel count or package type. Always verify pin-to-pin compatibility and electrical parameter equivalence before swapping components in an existing design.
