The 74HCT4053PW-Q100 is a quad analog multiplexer/demultiplexer, part of the 74HCT range of low-power Schottky TTL family. It is classified as an interface device, paralleling the types of switches, multiplexers, and demultiplexers.

The 74HCT4053PW-Q100 provides single-pole, double throw (SPDT) analog switching functions when single logic control inputs are used (A to Y0 and B to Y1). When two logic control inputs are used (A and B), it functions as a multiplexer channel selector allowing one of four channels (Y0 to Y3) to be selected. There are two versions of the 74HCT4053PW-Q100 available; the non-inverting version and the inverting version. The non-inverting version features independent active-low control inputs A and B, whereas the inverting version features a common active-low control input A and a common active-high control input B.

The 74HCT4053PW-Q100 multiplexer/demultiplexer is based on a four channel single-pole, double throw (SPDT) analog switch which is designed to maintain an identical on-resistance of 250Ω on each switch. It is designed to have low OFF leakage current to prevent false switching, and the high ON resistance allows very low power output devices to be used as the control inputs. Additionally, latched control inputs enable multiple demultiplexing, meaning it is possible to switch between multiple output pins with a single control signal.

The 74HCT4053PW-Q100 multiplexer/demultiplexer has a wide range of applications in both digital and analog circuits. In digital systems it can be used to route signals from multiple sources to multiple destinations, and in analog systems it can be used to route signals from a single source to multiple destinations. It can also be used for multiplexed control for systems with multiple control channels, such as memory matrices, where the multiplexers are used to select individual memory cells from a matrix of cells.

The working principle of the 74HCT4053PW-Q100 is relatively simple. The multiplexer is designed to switch between four channels, depending on the logic levels at the control inputs A and B. The logic levels at A and B determine which of the four output channels is switched to the output. The control inputs are used to control the analog switch, which is a simple SPST analog switch. The switch is used to route one of the four input channels to its output channel by either closing or opening it, depending on the logic levels at the control inputs. The output channel is routed to the output terminal, which is the multiplexer’s output terminal.

In summary, the 74HCT4053PW-Q100 is an interface device of the 74HCT family low-power Schottky TTL. It is a quad analog multiplexer/demultiplexer device with two versions, non-inverting and inverting. It has a wide range of applications in both digital and analog circuits and works by switching between four channels depending on the logic levels at the control inputs A and B. It is used to route signals from multiple sources to multiple destinations in digital systems, route signals from a single source to multiple destinations in analog systems, and multiplexed control for systems with multiple control channels.
