74HC4066; 74HCT4066
Quad single-pole single-throw analog switch
[1] Typical values are measured at T
amb
= 25 C.
[2] At supply voltages (V
CC
 GND) approaching 2 V, the analog switch ON resistance becomes extremely non-linear. Therefore it is
recommended that these devices be used to transmit digital signals only, when using these supply voltages.
