The MAX4899E/MAX4899AE analog multiplexers combine the low on-capacitance (CON) and low on-resistance (RON) necessary for high-performance switching applications. These devices are designed for USB 2.0 high-speed applications at 480Mbps. The MAX4899E/MAX4899AE also handle all the requirements for USB low- and full-speed signaling.
The MAX4899E is a dual 3:1 multiplexer whereas the MAX4899AE is a dual 4:1 multiplexer. The MAX4899E/MAX4899AE feature two digital inputs, C0 and C1, to control the analog signal path. Typical applications include switching a USB connector between USB and other operations such as serial communications, audio, and video.
An enable input (active-low EN) is provided to disable all channels and place the device into a high-impedance (off) state, as well as reducing power consumption.
The MAX4899E/MAX4899AE operate from a 2.7V to 3.6V power-supply voltage and are protected against +5.5V shorts to COMA- and COMA+. In addition, COMA+ and COMA- are normally connected to outside circuitry and feature ±15kV ESD protection. The MAX4899E/MAX4899AE are available in a 3mm x 3mm, 16-pin TQFN package and operate over the -40°C to +85°C temperature range.
