CD74HC4066PWG4

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4066PWG4 is a high-speed CMOS quad bilateral switch manufactured by Texas Instruments. It integrates four independent single-pole single-throw (SPST) analog switches within a 14-pin Thin-Shrink Small Outline Package (TSSOP). The device operates on a single supply voltage ranging from 2 V to 10 V, with a maximum power supply current of 16 µA. Key electrical specifications include a maximum on-resistance of 60 Ohms, a typical propagation delay of 12 ns, and an off-state leakage current of 100 nA. It supports a bandwidth of 200 MHz and functions reliably across an extended industrial temperature range from -55°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific ordering suffix corresponds to the TSSOP-14 package variant. Ensure compliance with RoHS directives and check for any recent Product Change Notices regarding manufacturing site updates or material substitutions prior to finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required within a compact surface-mount footprint. The TSSOP-14 package offers space efficiency compared to standard SOIC variants. Consider the 2 V to 10 V operating range to ensure compatibility with the system's power rails. Evaluate the 60 Ohm on-resistance limit against the application's signal integrity requirements to prevent excessive voltage drop.
