TS5A3159QDBVRQ1 Integrated Circuits (ICs)

The TS5A3159QDBVRQ1, manufactured by Texas Instruments, is a quad single-pole/single-throw (SPST) analog switch and multiplexer, combining both functions into one device. It is designed to provide the electrical switching and signal selection needed for analog signal switching and routing. The device features low switch ON resistance, which helps it maintain high signal fidelity even in applications requiring high signal levels. This device is suitable for a wide range of applications, such as audio and video signal routing, instrumentation, communications, and other electronic systems.

The TS5A3159QDBVRQ1 is a single package containing four, independent, analog signal switches and a two-channel multiplexer. Each signal switch can be enabled or disabled through the Input Enable pins, allowing the signal to be switched on and off, while the multiplexer can be used for signal routing by selecting one of two input channels based on the state of the select input pin. The device also features an active low enable pin, which enables the device to be shut down in order to save power.

When the select and enable pins are at the active low state, the switch is enabled and the multiplexer is then selected. The device then selects one of the two input channels and switches the corresponding output pin to the active ON state. Meanwhile, the other output pin of the device is connected to the logic low state. This enables the device to route the selected signal from the selected input channel to the output pin associated with that channel. Conversely, when the enable pin goes to the active high state, the device is disabled and all four signal switches are forced into the OFF state.

The TS5A3159QDBVRQ1 is ideal for applications requiring both signal switching and multiplexing. It has a low switch ON resistance, which helps it maintain high signal fidelity even in applications requiring high signal levels. This makes it an excellent choice for analog signal routing and switching in audio and video routing, instrumentation, communications, and other electronic systems.
