Functional Description

? Quad Bilateral Switch

General

The 74VHC4066AFT is high-speed, low-voltage drive QUAD BILATERAL SWITCH fabricated with silicon gate

C2MOS technology.

In 3 V and 5 V systems these can achieve high-speed operation with the low power dissipation that is a feature

of CMOS.

It consists of four independent high speed switches capable of controlling either digital or analog signals while

maintaining the CMOS low power dissipation.

The switches for each channel are turned ON by the control pin digital signals.

Control pin is equipped with a newly developed input protection circuit that avoids the need for a diode on the

plus side (forward side from the input to the VCC). As a result, for example, 5.5 V signals can be permitted on the

inputs even when the power supply voltage to the circuits is off. As a result of this input power protection, the

74VHC4066AFT can be used in a variety of applications, including in the system which has two power supplies,

and in battery backup circuits.
