74AHC1G66; 74AHCT1G66
Single-pole single-throw analog switch
[1] To avoid drawing V
CC
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 V
CC
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 Yand Z may not exceed V
CC
or GND.
[2] Applies to control signal levels.
