CD74HCT4066QPWRQ1

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HCT4066QPWRQ1 is an automotive-grade quad bilateral switch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features four independent single-pole single-throw (SPST) analog switches in a TSSOP-14 package. The device supports bidirectional signal flow with low on-resistance and high off-isolation. It is designed for harsh environments, functioning reliably between -40°C and +125°C. Key electrical parameters include a maximum propagation delay of 20 ns and a maximum power supply current of 2 µA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific revision level and tape-and-reel quantity upon ordering. Confirm that the component meets the required AEC-Q100 grade specifications for the intended automotive application environment. Ensure compatibility with existing PCB footprint designs utilizing the TSSOP-14 package dimensions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when automotive reliability is mandatory and TTL-compatible control signals are available. It serves as a direct functional replacement for standard commercial variants in applications requiring extended temperature ranges and validated automotive quality standards without altering the circuit topology.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the CD74HCT4066 family of high-speed CMOS analog switches. The 'Q' suffix indicates automotive qualification, while 'PWR' denotes the TSSOP-14 surface-mount package. It shares pinout compatibility with commercial counterparts but adheres to stricter manufacturing controls for automotive deployment.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The CD74HC4066QPWRQ1 is a non-TTL variant offering wider voltage tolerance. Standard CD74HCT4066 devices lack automotive certification. Verify pinout alignment before substituting with other quad analog switches.
