DUAL BILATERAL ANALOG
SWITCH

SOP-8
DESCRIPTION
The U74LVC2G66 is a dual bilateral analog switch which is
designed for 1.65V to 5.5V operation. This switch can handle
both analog and digital signals and permits signals with
amplitudes of up to 5.5 V (peak) to be transmitted in either
direction. Each switch section has enable-input control (C). If
the voltage applied to C is at high-level, the associated switch
section is turned on.
