UNISONIC TECHNOLOGIES CO., LTD U74AHC1G66 CMOS IC BILATERAL SWITCH 3 2 1 5 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.

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.
