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 device
suitable for high frequency data switching. Each switch con-
ducts 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 is available in a 12-lead LFCSP and a 10-lead mini
LFCSP. These packages make the ADG772 the ideal solution for
space-constrained applications.
