MAX4989ETD+T

Analog Switches - Special Purpose Overview

The MAX4989ETD+T is a bidirectional 2-of-4 USB 2.0 crosspoint switch designed for routing low-, full-, and Hi-Speed signals up to 480Mbps. It operates from a single +2.7V to +5.5V supply with an internal charge pump for rail-to-rail swing. The device features a high-impedance shutdown mode reducing supply current to 100nA (typ). Key electrical parameters include a typical on-resistance of 5Ω, a -3dB bandwidth of 1GHz, and a typical supply current of 1µA when enabled. It is housed in a 14-pin, 3mm x 3mm TDFN package and operates over the extended -40°C to +85°C temperature range.

Analog Switches - Special Purpose Feature Summary

• Supports switching any two of four USB differential pairs via a simple three-input control logic interface.
• Features an internal charge pump enabling full rail-to-rail signal swing for Hi-Speed USB applications.
• Provides a high-impedance shutdown mode that significantly reduces power consumption.
