Multiplexers
General Description
The MAX4899E/MAX4899AE analog multiplexers com-
bine the low on-capacitance (C_ON) and low on-resis-
tance (R_ON) 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 con-
trol the analog signal path. Typical applications include
switching a USB connector between USB and other oper-
ations such as serial communications, audio, and video.
An enable input (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 COM_A- and COM_A+. In addition,
COM_A+ and COM_A- 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.
