Quad Analog Switch/Multiplexer/Demultiplexer
Quad Analog Switch/
Multiplexer/Demultiplexer
High–Performance Silicon–Gate CMOSThe MC74VHC4066 utilizes silicon–gate CMOS technology to
achieve fast propagation delays, low ON resistances, and low
OFF–channel leakage current. This bilateral
switch/multiplexer/demultiplexer controls analog and digital voltages
that may vary across the full power–supply range (from VCC to GND).
The VHC4066 is identical in pinout to the metal–gate CMOS
MC14066 and the high–speed CMOS HC4066A. Each device has four
independent switches. The device has been designed so that the ON
resistances (RON) are much more linear over input voltage than RON
of metal–gate CMOS analog switches.
The ON/OFF control inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LSTTL
outputs. For analog switches with voltage–level translators, see the
VHC4316. Fast Switching and Propagation Speeds High ON/OFF Output V oltage Ratio Low Crosstalk Between Switches Diode Protection on All Inputs/Outputs Wide Power–Supply Voltage Range (VCC – GND) = 2.0 to 12.0 Volts Analog Input Voltage Range (VCC – GND) = 2.0 to 12.0 Volts Improved Linearity and Lower ON Resistance over Input V oltage
