74HC2G66; 74HCT2G66

Dual 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.

[2]

Typical values are measured at Tamb = 25 °C.

Table 8.

ON resistance for 74HC2G66 and 74HCT2G66

At recommended operating conditions; voltages are referenced to GND (ground 0 V); for graph see Figure 8.
