The PI5A4684GAEX is an analog switch and multiplexer, or multiplexer/demultiplexer, integrated circuit (IC) manufactured by Diodes Incorporated. This versatile device is well suited for a variety of high-bandwidth signals in a variety of applications, and is available in an 8-bit wide package with a low-power system. This device is ideal for quickly switching between multiple amplifiers, channels, analog-to-digital converters (ADCs), or for quickly routing signals between analog circuitry or applications.

The PI5A4684GAEX is a bi-directional analog switch, allowing signals to pass in either direction. It works by using two independent channels, each with its own Enable input, and a common Select input. When a channel is enabled, its Enable input is connected to ground, and the Select input is connected to either the channel’s source or its drain. The Enable inputs of both channels can be independently enabled, allowing the IC to function as either a multiplexer, selecting one of two inputs, or as a demultiplexer, allowing one of two outputs to be selected.

The power consumption of the PI5A4684GAEX is very low at a mere 2.5mA for the entire package. This allows for power efficient design by reducing the number of power supply components and direct current (DC) power sources in the overall circuit design. The device operates from a single 3V power supply and responds to logic levels from 0V to 3V for both enable and select signals.

The PI5A4684GAEX can be used in a variety of applications due to its unique bi-directional interface. It is most commonly used in applications such as audio routing and mixing, digital-to-analog (D/A) and analog-to-digital (A/D) conversion, intercom systems, video routing and switching, amplifier switching, video scan converters, test and measurement applications, and industrial control systems. It is well suited for faster-than-optimum speeds and High-speed switching applications. The device is designed to provide excellent noise performance, fast switching speeds and very low power consumption.

The PI5A4684GAEX switch works by controlling the flow of the signal. An electrical circuit is formed between the source, common select, and drain of the switch. When the Enable input is held low, the channel between the source and the drain is activated and the signal passes from one side to the other. When the Select input is low, the signal passes from the source to the drain, or vice versa, depending on the input and output points selected.

In summary, the PI5A4684GAEX provides a reliable, low-power, bi-directional analog switch, multiplexer and demultiplexer solution, that can be used in a variety of applications involving high bandwidth signals. It is easy to use, requires minimal external components, and is designed to provide excellent noise performance and fast switching speeds. Perfect for audio routing and mixing, digital-to-analog and analog-to-digital conversion, intercom systems, and video routing and switching, the PI5A4684GAEX provides a robust solution for those looking for an effective, low-power multiplexer/demultiplexer for their applications.
