Key Features
- AEC-Q100 automotive-qualified 8-channel analog MUX/DEMUX for in-vehicle signal routing
- 180 MHz nominal bandwidth with 2 V to 10 V (VCC-VEE) supply range for versatile analog routing
- Supports bipolar supply configurations down to -6 V VEE enabling true analog signal switching through ground
Applications
The CD74HC4051QPWRQ1 is designed for automotive sensor multiplexing applications such as battery management systems and ADAS sensor hubs that need to route 8 analog channels to a single ADC input rail. Its 180 MHz bandwidth and wide 2 V to 10 V supply range allow it to handle audio, sensor, and control signals in harsh automotive environments. The AEC-Q100 qualification and Pb-free 16-pin SOIC packaging ensure long-term reliability in under-hood and infotainment modules.

Frequently Asked Questions
What bandwidth does the CD74HC4051QPWRQ1 support, and does it meet requirements for audio or high-frequency sensor multiplexing?
The CD74HC4051QPWRQ1 has a nominal bandwidth of 180 MHz, which is more than sufficient for audio-band signals up to 20 kHz and many industrial sensor outputs up to several MHz. This makes it suitable for multiplexing microphone arrays, vibration sensors, or analog front-end channels in automotive infotainment and condition-monitoring systems.
Can the CD74HC4051QPWRQ1 operate with a split supply to pass signals that swing below ground?
Yes, the CD74HC4051QPWRQ1 supports a negative supply voltage down to -6 V on the VEE pin, enabling bipolar operation with a total VCC-VEE range of up to 10 V. This allows analog signals that swing between -4.5 V and +4.5 V to pass through the 8 channels without clipping, which is useful in AC-coupled automotive audio and bridge sensor readout circuits.
How does the automotive Q1 qualification of CD74HC4051QPWRQ1 differentiate it from the commercial CD74HC4051 in a vehicle design?
The QPWRQ1 suffix confirms AEC-Q100 Grade 1 qualification, meaning the device is tested and screened to automotive temperature and reliability standards for operation from -40°C to +125°C. Commercial-grade CD74HC4051 variants are not subject to these stress tests, so using the Q1 part provides documented qualification evidence required by Tier-1 automotive suppliers and OEM design review gates.
