General description

The HEF4066B provides four 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.

The HEF4066B is pin compatible with the HEF4016B but exhibits a much lower ON

resistance. In addition the ON resistance is relatively constant over the full input signal

range.
