DESCRIPTION
The 74LVQ4066 is a low voltage CMOS QUAD
BILATERAL SWITCH fabricated with sub-micron
silicon gate and double-layer metal wiring C
2
MOS
technology.
It is ideal for low power and low noise 3.3V
applications and each switch is designed to
handle both analog and digital signals.
The switches permit signals with amplitudes up to
V
CC
(peak) to be transmitted in either direction
without relevant propagation delay and without
generating additional ground bounce noise.
It has an ON-Resistance which is greatly reduced
in comparison with 74HC4066.
It is provided of four individual enable inputs to
control the switches; the switch is ON when the C
input is held high and OFF (High Impedance)
when C is held low.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them ESD immunity and transient excess voltage.
