What is the difference between a bus switch and an analog switch?

A bus switch is a device developed for the purpose of transmitting and switching digital signals at high speed. An analog switch, on the other hand, is a device that transmits and switches analog signals such as audio signals.

Therefore, specifications for analog characteristics (sine wave distortion, feedthrough, crosstalk, etc.) are listed on the datasheet. (Table-1)

Table-1 74HC4053 data sheet (Analog characteristics)

Among the bus switches, there are products that handle high-speed (GHz band) signals, and the frequency bandwidth (BW) characteristics etc. are written on those products.
