ADG787 - Analog Devices

ADG787 2.5 OHM CMOS Low Power Dual 2:1 Mux/Demux USB1.1 Switch

The ADG787 is a low voltage, CMOS device that contains two independently selectable single-pole, double-throw (SPDT) switches. It is designed as a general analog-to-digital switch and can also be used for routing USB 1.1 signals. This device offers low on resistance of typically 2.5 Ω, making the part an attractive solution for applications that require low .
