MAX4899AEETE+T

P1-P3P4-P6P7-P9P10-P12P13-P14
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, C
0
and C
1
, 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.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
