The MC74HC4066ADG belongs to the family of MOS integrated circuits from ON Semiconductor and is categorized as an analog switch, multiplexer, demultiplexer. This switch is designed with Schmitt triggers which offer an additional noise immunity advantage over basic CMOS switches. It is also designed to provide a wide voltage range of 2.0 V to 6.0 V utilizing only low power consumption. The device offers a high-performance CMOS logic with a wide voltage range, TTL logic compatibility and low static power consumption. Designed for switching analog signals, the device has GPIO ports for controlling the switches.

The MC74HC4066ADG is a low-power, low-voltage CMOS device used as a general-purpose analog switch or to select signals from multiple inputs. It is used in virtually any application requiring signals from multiple sources to be connected to one device. It is often used in audio switching applications, such as volume and tone control. Other applications of the analog switch include the selection of the input sources for low-power amplifiers, switching between audio and video devices, switching between digital and analog signals, and selecting signals from multiple source.

The MC74HC4066ADG is designed to integrate four independent single-pole single-throw (SPST) switches, two double-pole single-throw (DPST) switches and two triple-pole single-throw (TPST) switches. Each switch is controlled individually with a low- to high-voltage input. The maximum off-state resistance, when all switches are open, is 250 ohms. The maximum on-state resistance is typically 0.03 ohms. The switching threshold is approximately 5 V when the input is low and 0.8 V when the input is high. The circuit ensures a low on-resistance and an accurate switching threshold voltage.

The MC74HC4066ADG is also equipped with an active-low reset input. This pin can be used to reset the device and ensure that the switches are off. Additionally, an active-low enable input is provided, which can be used to enable and disable the circuits. The enable pin can be connected to a separate logic circuit if needed. A wide range of frequencies can be used, from 10 kHz to 15 MHz, depending on the input voltage. The device also features an analog input capacitor which can be used to reduce EMI and ground noise.

The MC74HC4066ADG has several features, such as low static power consumption, low-to-high voltage input and TTL logic compatibility, that make it an ideal choice for many applications. The device is robust and very reliable, making it a popular choice for analog switches, multiplexers, demultiplexers and other switching circuits. It is a great choice for any project that requires reliable, low-power and low-voltage signal switching.
