What are the key features of CD74HC4051MG4?
- 8-channel single-ended analog multiplexer with bidirectional operation supporting signals from DC to 40 MHz bandwidth
- Wide 2 V to 10 V supply range including dual-supply operation with negative rail down to -6 V for AC signal switching
- Low on-resistance below 80 ohms across the full 8 channels enabling accurate analog signal routing in data acquisition systems
What is CD74HC4051MG4 used for?
The CD74HC4051MG4 is used in data acquisition systems to route one of 8 analog sensor signals to a single ADC input, reducing the number of converters required. It is also used in audio signal routing, test equipment, and programmable gain amplifier circuits where different signal paths must be selected under software control. Industrial process controllers and battery-powered instruments benefit from its 2 V to 10 V supply flexibility and low on-resistance.

Frequently Asked Questions
How many analog channels can CD74HC4051MG4 switch, and what is the on-resistance per channel?
The CD74HC4051MG4 switches 8 analog channels with a typical on-resistance below 80 ohms per channel at 4.5 V supply. This on-resistance is low enough for most sensor signal routing applications where the load impedance is above 10 kilohms, keeping the voltage drop below 1% of full-scale signal amplitude.
Can CD74HC4051MG4 switch AC audio signals, and what supply configuration does this require?
The CD74HC4051MG4 can switch AC audio signals by using a split supply, for example +5 V on VCC and -5 V on VEE, allowing signals to swing from -4.5 V to +4.5 V through the switch. This dual-supply configuration supports audio signals up to 10 Vpp with total harmonic distortion below 0.1% at 1 kHz, making it suitable for audio mixing and routing applications.
How does CD74HC4051MG4 reduce ADC channel count in an 8-sensor data acquisition design?
By connecting 8 sensor outputs to the CD74HC4051MG4 analog inputs and the common output to a single 12-bit ADC, a microcontroller can sequentially select each channel using 3 digital control pins. This replaces 8 individual ADC channels with 1, reducing BOM cost significantly while achieving sampling rates up to 100 kHz per channel if multiplexed at 800 kHz total throughput.
What 16-pin package does CD74HC4051MG4 use, and is it compatible with automated PCB assembly?
The CD74HC4051MG4 uses a 16-pin SOIC package (JESD-30 code R-PDSO-G16) with 1.27 mm pin pitch and a body width of 3.9 mm. This standard package is fully compatible with automated SMT pick-and-place and reflow soldering at temperatures up to 260°C, meeting JEDEC J-STD-020 MSL classification for industrial assembly processes.
