NXP Semiconductors 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 T
amb
= 25 C.
