Product data sheet
1. General description
The 74LVC2G66 is a high-performance, low-power, low-voltage, Si-gate CMOS device.
The 74LVC2G66 provides two analog switches. Each switch has a input and output (pins
Y and Z) and an active HIGH enable input (pin E). When pin E is LOW, the analog switch
is turned off.

To avoid drawing V
CC
current out of terminal nZ, when switch current flows in terminal nY, the voltage drop
across the bidirectional switch must not exceed 0.4 V. If the switch current flows into terminal nZ, no V
CC
current will flow out of terminal nY. In this case there is no limit for the voltage drop across the switch.
For overvoltage tolerant switch voltage capability, see the 74LVCV2G66.
Applies to control signal levels.
