General Description  
Features  
The MAX14778 dual 4:1 analog multiplexer supports  
analog signals up to Q25V with a single 3.0 to 5.5V  
supply. Each multiplexer has separate control inputs to  
allow independent switching, making the device ideal for  
multiplexing different communications signals with the  
same connector pins. Extended ESD protection of Q6kV  
(Human Body Model) enable direct interfacing to cables  
and connectors.

The MAX14778 features a low 1.5I (max) on-resistance  
and 3mI (typ) flatness to maximize signal integrity over  
the entire common-mode voltage range. Each multiplex-  
er can carry up to 300mA of continuous current through  
the multiplexer in either direction.

The MAX14778 supports switching of full-speed USB 1.1  
signals (12Mbps) and RS-485 data rates of up to 20Mbps.  
Ordering Information appears at end of data sheet.  
The MAX14778 is available in a 20-pin (5mm x 5mm)  
TQFN package and is specified over the -40NC to +85NC  
extended temperature range.
