General description

The 74LVC2G66 is a low-power, low-voltage, high-speed Si-gate CMOS device.

The 74LVC2G66 provides two single pole, single-throw analog switch functions. Each

switch has two input/output terminals (nY and nZ) and an active HIGH enable input (nE).

When nE is LOW, the analog switch is turned off.

Schmitt-trigger action at the enable inputs makes the circuit tolerant of slower input rise
