Overview
The MC74LVX4066DR2G is a quad analog switch manufactured by onsemi using silicon-gate CMOS technology. It operates within a supply voltage range of 2.0 V to 6.0 V and supports analog signals across the full power-supply range. The device features four independent bilateral switches with low ON resistance (typically 25 Ω at 3.0 V) and low OFF-channel leakage current (1.0 µA max). It provides fast propagation delays, high linearity, and diode protection on all inputs and outputs. Available in SOIC-14 and TSSOP-14 packages, it is RoHS compliant and designed for applications requiring precise signal routing.
Feature Summary
- High-performance silicon-gate CMOS technology ensures fast switching speeds and low ON resistances.
- Bilateral switch design controls analog and digital voltages varying across the full power-supply range.
- Improved linearity and lower ON resistance compared to metal-gate CMOS alternatives like MC14066.
- Integrated diode protection on all inputs and outputs safeguards against voltage transients.
Applications
- Analog signal multiplexing and demultiplexing
- Digital-to-analog and analog-to-digital conversion interfaces
- Audio and video signal routing
Procurement Notes
Verify the ordering suffix 'DR2G' corresponds to the SOIC-14 package in Tape & Reel configuration. Confirm RoHS compliance status and Pb-Free designation as specified in the manufacturer's documentation. Ensure the component matches the active or discontinued status indicated in the latest datasheet revision history before procurement.
Selection Notes
Select this component when a quad analog switch is required with a wide 2.0 V to 6.0 V operating voltage range. It is suitable for designs needing low crosstalk and high isolation between channels. Consider the SOIC-14 package for standard surface-mount assembly. Verify that the maximum analog input voltage does not exceed the supply rails to prevent damage.
Part Context
This device belongs to the LVX series of high-speed CMOS logic components from onsemi. It serves as a modern replacement for older metal-gate CMOS analog switches such as the MC14066 and HC4066A. The pinout remains identical to these legacy parts, facilitating direct upgrades in existing circuit designs while offering improved electrical performance and lower power consumption.
Replacement Considerations
Publicly confirmed substitutes include the MC74LVXT4066DR2G and MC74VHC4066DR2. Verify compatibility regarding ON resistance specifications and control input voltage levels when substituting.
