The M74HC4851YTTR is an interface device belonging to the categories of analog switches, multiplexers, and demultiplexers. It is a kind of 8:1 multiplexer/demultiplexer, providing 8-channel address selection with the control of a single active-high chip enable (CE) line and active-low address select (AS )lines. This device contains four integrated multiplexers/demultiplexer circuits with two enables per circuit to allow 8 lines from one channel to be connected to one line from any of the other seven channels.

The M74HC4851YTTR is fabricated using CMOS that features low power consumption, good static performance and high noise exemption. It requires minimal external control elements and thus has very low driving requirements, which leads to the performance of a wide dynamic range and an optimized on-chip power IO. It is an ideal device for use in high speed, low power applications.

This device has various applications in communication systems, data storage devices and computers. It can be used to connect multiple peripherals to a single computer port, as well as providing a flexible solution to switch data between multiple channels and multiple devices. The M74HC4851YTTR also has applications in audio test equipment and power supply control.

The working principle of the M74HC4851YTTR is that it is controlled by a single line of active-high chip enable and active-low address select lines. When one address select line is active and the chip enable line enabled, the M74HC4851YTTR will select the corresponding channel to be connected to the single line. The multiplexers/demultiplexers internally select 8-line sets, depending on the active address select and chip enable lines. The selected 8-line set is then connected to the single output line.

The M74HC4851YTTR provides a very useful and cost effective solution for connecting multiple peripherals to a single computer port. Compared to a non-integrated circuit, using the M74HC4851YTTR eliminates circuit redundancies and simplifies design. With its low power requirements, high noise immunity and a wide dynamic range, the M74HC4851YTTR has a wide array of applications in audio test equipment, power supply control and other communication and data storage equipment.
