74AHC1G66; 74AHCT1G66

Single-pole single-throw analog switch

[1]

To avoid drawing VCC current out of pin Z, when switch current ﬂows in pin Y, the voltage drop across the bidirectional switch must not

exceed 0.4 V. If the switch current ﬂows into pin Z, no VCC current will ﬂow out of terminal 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.

Applies to control signal levels.
