MC74LVXT4066
Quad Analog Switch/
Multiplexer/Demultiplexer
High–Performance Silicon–Gate CMOS
The MC74LVXT4066 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 LVXT4066 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 LSTTL
outputs. The input protection circuitry on this device allows
overvoltage tolerance on the ON/OFF control inputs, allowing the
device to be used as a logic–level translator from 3.0V CMOS logic to
5.0V CMOS Logic or from 1.8V CMOS logic to 3.0V CMOS Logic
while operating at the higher–voltage power supply.
The MC74LVXT4066 input structure provides protection when voltages
up to 7V are applied, regardless of the supply voltage. This allows the
MC74LVXT4066 to be used to interface 5V circuits to 3V circuits.
• Fast Switching and Propagation Speeds
• High ON/OFF Output Voltage Ratio
• Low Crosstalk Between Switches
• Diode Protection on All Inputs/Outputs
• Wide Power–Supply Voltage Range (VCC – GND) = 2.0 to 6.0 Volts
• Analog Input Voltage Range (VCC – GND) = 2.0 to 6.0 Volts
• Improved Linearity and Lower ON Resistance over Input Voltage
than the MC14016 or MC14066
• Low Noise
