High–Performance Silicon–Gate CMOS
The 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 V
CC
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
(R
ON
) are much more linear over input voltage than R
ON
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 Voltage Ratio
• Low Crosstalk Between Switches
• Diode Protection on All Inputs/Outputs
• Wide Power–Supply Voltage Range (V
CC
– GND) = 2.0 to 12.0 Volts
• Analog Input Voltage Range (V
CC
– GND) = 2.0 to 12.0 Volts
• Improved Linearity and Lower ON Resistance over Input Voltage than
the MC14016 or MC14066
• Low Noise
• Chip Complexity: 44 FETs or 11 Equivalent Gates
