GENERAL DESCRIPTION
The ADG772 is a low voltage, CMOS device that contains two
independently selectable single-pole, double throw (SPDT)
switches. It is designed as a general-purpose switch and can be
used for routing both USB 1.1 and USB 2.0 signals.
This device offers a data rate of 1260 Mbps, making the part
suitable for high frequency data switching. Each switch
conducts equally well in both directions when on and has an
input signal range that extends to the supplies. The ADG772
exhibits break-before-make switching action.
The ADG772 comes in a 12-lead LFCSP, and a 10-lead mini
LFCSP. These packages make the ADG772 the ideal solution for
space-constrained applications.
