The MC74HC4852AN is a Dual 4-Channel Analog Multiplexer/Demultiplexer IC from On Semiconductor which contains two 4-Channel, Bi-directional 4:1 Mux/Demux devices. The IC is a 4:1 multiplexer providing 16 distinct channels through which an analog signal can be directed.

The MC74HC4852AN device is typically used in applications where it is necessary to either select one of four analog signals for application to a given load element or, for multiplexing of up to four analog signals. The MC74HC4852AN can be used to multiplex both audio and video information.

The functionality of this device is based on the operation of its channel selection inputs, addresses, and data inputs. The four address inputs select one of the four channels. A high on the Enable line allows a logic high or logic low to be transmitted through the multiplexer. All four channels are active when the Enable input is low.

The MC74HC4852AN is available in a 16-pin Dual In-line Package. The device features a positive supply voltage range of 2.0 V to 7.0 V, with a maximum operating frequency of 15 MHz. It is rated to function over an operating temperature range of -55° C to +125° C.

The MC74HC4852AN is designed using the advanced Schottky TTL logic family which enhances its operation speed. In addition, the device withstands static discharge and transient voltage for higher reliability and offers pin-to-pin compatibility to other multiplexers in this family.

The working principle of the MC74HC4852AN is based on the control of its channel selection inputs which determine the route of analog signal flow. When the Enable input is low, all four channels are active. When the Enable input is high, the logic state on the four address inputs determines the active channel. The four data channels are connected together at the output such that when one channel is selected the other three are disabled.

In summary, the MC74HC4852AN is a 4-channel, 4:1 multiplexer/demultiplexer IC with wide applications in audio/video signal switching and distribution. The device integrates Schottky TTL logic family to enhance its operation speed, making it suitable for audio/video switching applications. The MC74HC4852AN is packaged in a small 16-pin DIP package, making it easy to use in dense printed circuit board designs.
