CD74HCT4066QM96Q1 Datasheet/PDFCD74HCT4066QM96Q1 is an analog switch, multiplexer, and demultiplexer manufactured by Texas Instruments, released in 2009. It consists of four analog switches, each of which can be independently enabled and disabled, allowing the device to either route signals in an analog circuit or just block them.
The control inputs of the switches are all digital (complementary). When both inputs are LOW, the switch is OFF; and when both inputs are HIGH, the switch is ON. The device also has an ENABLE input that is used to turn all the switches at once either ON or OFF. This makes the CMOS switches useful for quickly routing analog signals in distributed processing or multiplexing and demultiplexing operations.
The device has a typical switch ON resistance of 130 ohms and a maximum resistance value of 500 ohms. This makes it suitable for low impedance applications, such as audio and video signal processing. The usual operating voltage is between 3V and 15V, allowing for compatibility with a wide variety of control and switching signals.
The CD74HCT4066QM96Q1 offers a wide range of applications, since it can be used to either route digital or analog signals. It can be used in analog multiplexers, to select a single output from multiple input sources, or demultiplexers, to select multiple outputs from a single source. It is also used in DACs to switch the digital inputs into analog outputs, in optical applications as a switch for optical fibers, and in audio applications as a sixth order filter. Because of its low power consumption, the device is also used in power-efficient portable audio products.
In summation, the CD74HCT4066QM96Q1 is a versatile analog switch, multiplexer and demultiplexer. It offers a wide range of applications, from audio and video signal processing, optical applications and DACs, to power-efficient portable audio products. Its features, such as its low power consumption and wide operating voltage, make it a great choice for any application that requires switching or routing of analog signals.
