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.
