Functional Description
• Quad Bilateral Switch

General
The 74HC4066FT is a high speed CMOS QUAD BILATERAL SWITCH fabricated with silicon gate CMOS
technology. It consists of four independent high speed switches capable of controlling either digital or analog
signals while maintaining the CMOS low power dissipation.
Control input (C) is provided to control the switch. The switch turns ON while the C input is high, and the switch
turns OFF while low.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features
(1) Wide operating temperature range: Topr = -40 to 125
(2) Low power dissipation: ICC = 1.0 μA (max) at VCC = 6.0 V, Ta = 25
(3) High noise immunity: VNIH = VNIL = 28 % VCC (min)
(4) Low ON resistance: RON = 50 Ω (typ.) at VCC = 9.0 V, VI/O = VCC or GND
(5) High degree of linearity: THD = 0.05 % (typ.) at VCC = 4.5 V
