DESCRIPTION
4
The U74AHC1G66 is an analog switch which transmits signals from
pin(Y or Z) to pin (Z or Y) with an active HIGH enable input pin (E).
When pin E is LOW, the switch is turned off.

Note 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
3. To avoid drawing Vcc current out of pin Z, when switch current flows into pin Y, the voltage drop across the
bidirectional switch must not exceed 0.4V. If the switch current flows into pin Z, no Vcc current will flow out of
pin Y. In this case there is no limit for the voltage drop across the switch, but the voltage at pins Y and Z may
not exceed Vcc or GND.

Note 4. With supply voltages at or near 2V, the analog switch on-state resistance becomes very nonlinear. Only
digital signals should be transmitted at these low supply voltages.
