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

and fall times across the entire VCC range from 1.65 V to 5.5 V.
