ervoltage Indicator Output FN6969 Rev 1.00 September 19, 2013 The ISL54224 is a single supply dual 2:1 multiplexer that can operate from a single 2.7V to 5.25V supply. It contains two SPDT (Single Pole/Double Throw) switches configured as a DPDT. The part was designed for switching of USB data signals in portable battery powered products. The 6.5Ωswitches were specifically designed to pass USB high speed/full speed data signals. They have high bandwidth and low capacitance to pass USB high speed data signals with minimal distortion. The ISL54224 has OVP circuitry on the D-/D+ com pins that opens the USB in-line switches w
