MC74VHC4066

Quad Analog Switch/

Multiplexer/Demultiplexer

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 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.

Features

• 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 12.0 Volts

• Analog Input Voltage Range (VCC − 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

• These Devices are Pb−Free and are RoHS Compliant
