The TS3A4751RGYR is a SP3T single-pole, three-throw analog switch, suitable for use as a multiplexer/demultiplexer (mux/demux) or a one-to-three distribution network in a wide range of applications. It features low on and off resistance, fast switching speeds and low leakage. The TS3A4751RGYR is designed for use in consumer, industrial, and automotive electronic systems.

Application Field

The TS3A4751RGYR provides robust signal integrity in a variety of applications. Its low on/off resistance and fast switching speeds make it suitable for use as an analog audio switch, while its low leakage makes it ideal for communications and security. Its wide operating range and low power consumption make it useful in mobile devices, such as cell phones, tablets, and wearables. Additionally, it can be used in industrial applications, such as electronic test and measurement and medical instruments.

Working Principle

The TS3A4751RGYR operates as a single-pole, three-throw analog switch by using a MOSFET as the internal switch. The switch is configured as an SP3T as required for mux/demux applications. The gate of the MOSFET is driven by two logic levels, one for the on and one for the off states. When the logic levels of the on/off inputs are different, the MOSFET is in the “off” state, and the corresponding output is in the high-impedance state. When the logic levels of the on/off inputs are the same, the MOSFET is “on” and the corresponding output is connected to its associated inputs. This switching mechanism allows the TS3A4751RGYR to work as a mux/demux or as a one-to-three distributors.
