CD74HC4051QM96Q1

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HC4051QM96Q1 is an automotive-grade, high-speed CMOS analog multiplexer/demultiplexer manufactured by Texas Instruments. It integrates eight independent bidirectional channels within a single 16-pin SOIC package. The device supports a single supply voltage range of 2V to 6V or dual supplies of ±1V to ±5V. Key electrical specifications include a maximum on-resistance of 130 ohms with a channel-to-channel matching of 5 ohms, a -3dB bandwidth of 180MHz, and an off-state leakage current of 400nA. It operates reliably across a temperature range of -40°C to 125°C and holds AEC-Q100 qualification for automotive applications.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'QM96G4Q1' matches the required automotive qualification and tape-and-reel packaging format. Confirm that the component meets the intended operating temperature range and voltage requirements for the target application before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when automotive reliability (AEC-Q100) is mandatory alongside high-speed analog switching. Compare against standard commercial grades if automotive certification is unnecessary. Ensure the 130-ohm on-resistance fits the signal integrity budget for the specific load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Texas Instruments CD74HC405x family of high-speed CMOS logic devices. The 'Q1' suffix denotes its qualification for automotive use, while 'M96' indicates the specific SOIC-16 package variant. It serves as a core switching element in mixed-signal circuits requiring robust performance in harsh environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

CD74HC4051M96Q1: Commercial equivalent without automotive qualification. CD74HC4051M96: Standard commercial version lacking Q1 suffix. Verify pin compatibility and electrical parameters before substituting.
