LC4966
Quad Bilateral Switch
Overview
The LC4966 is an IC that provides the same functions as
the MLC4066B and the MLC4066BH over an expanded
usable voltage range. The LC4966 provides four
bidirectional switch circuits. These circuits form a low-
impedance conducting path between the input and output
sides when the corresponding control input (CONT) is set
high, and form a high-impedance nonconducting open
circuit when the control input is set low.
