They are bidirectional switches, thus allowing any analog input to be used as an output and vice versa. The switches have low on-resistance and low off leakages. In addition, these devices have an enable control that, when high, disables all switches to their off state.\n\n## Key Specifications\n\n| Parameter | Value |\n| --- | --- |\n| Channels | 16 (analog mux/demux, bidirectional) |\n| Supply Voltage (HC) | 2 V to 6 V (analog input up to V<sub>CC</sub>) |\n| Supply Voltage (HCT) | 4.5 V to 5.5 V |\n| On-Resistance (typ) | 70 Ω @ V<sub>CC</sub> = 4.5 V;
