74HC1G66; 74HCT1G66

Single-pole single-throw analog switch

10.2 ON resistance

[1]

At supply voltages approaching 2 V, the ON resistance becomes extremely non-linear. Therefore it is recommended that these devices

be used to transmit digital signals only, when using this supply voltage.

ON resistance

At recommended operating conditions; voltages are referenced to GND (ground 0 V); for graph see Figure 7.
