CD74HC4066MG4

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4066MG4 is a high-speed CMOS logic quad bilateral switch manufactured by Texas Instruments. It integrates four independent single-pole single-throw (SPST) analog switches within a 14-pin Small Outline Integrated Circuit (SOIC) package. The device operates on a single supply voltage ranging from 2 V to 10 V and supports an extended industrial temperature range of -55°C to +125°C. Key electrical specifications include a maximum bandwidth of 200 MHz, a typical on-resistance of 70 ohms, and low power consumption with a maximum supply current of 2 µA. The component is lead-free and RoHS compliant.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as defined by Texas Instruments documentation. Confirm the package variant matches the required SOIC-14 footprint dimensions. Ensure the order quantity aligns with standard tube packaging configurations typically associated with this part number. Cross-reference the manufacturer date code against project lifecycle requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the CD74HC4066MG4 when a wide supply voltage range between 2 V and 10 V is required compared to HCT variants limited to 5 V. Choose this HC series over HCT if lower static power consumption is critical for battery-operated designs. Verify that the 70 Ω on-resistance meets the signal integrity requirements for the specific application bandwidth. Consider the 14-SOIC package constraints regarding thermal dissipation and board space availability.

Analog Switches, Multiplexers, Demultiplexers Part Context
