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 R 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 MC74L VXT4066 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 (V

• Analog Input Voltage Range (V

– GND) = 2.0 to 6.0 Volts

• Improved Linearity and Lower ON Resistance over Input Voltage

than the MC14016 or MC14066

• Low Noise
