TS5N118PWE4 is a logic-signal switch today and is widely used in multiplexers, decoders and many other fields. This article will explore the application field and working principle of TS5N118PWE4 in more detail to help understand and appreciate its functions.

Application Field

TS5N118PWE4 is generally used as a switch in multiplexers, decoders, and other electronic circuits. As a logic-signal switch, it works by connecting or disconnecting a signal path based on input logic states—such as a voltage or current. The device is particularly useful when controlling the input or output of a circuit, allowing for on-off switching of signals. It can also be used for time delays, threshold detection, and other such purposes.

In multiplexers and decoders, TS5N118PWE4 is used to control the flow of a signal from one source to multiple connection points. Its ability to switch quickly and reliably makes it ideal for applications such as digital-to-analog conversion, multiplexing, and logic gate circuits. Moreover, its logic-signal switch design ensures that the device functions properly in conditions with abrupt signal changes, such as when switching from one state to another using a low-voltage power source.

Working Principle

TS5N118PWE4 works by connecting or disconnecting a signal path based on input logic states. From a technical perspective, its logic-signal switch design utilizes an insulated gate bipolar transistor (IGBT) as an input switch along with a p-channel MOSFET. The IGBT is able to quickly switch to either its high or low logic states, depending on the level of the input voltage, and then open and close the signal path accordingly. The p-channel MOSFET acts as an output buffer and provides additional output current.

In order to properly operate, TS5N118PWE4 requires an input signal with a minimum of 3.3V. Once connected to an appropriate power source, the logic signal switch will be ready to switch in the logic signal range of 2V to 8V. The device also includes a static protection diode, which prevents damage due to static electricity. This diode provides extra protection when the device is switched repeatedly or is subject to large surges in voltage.

In addition to its static protection diode, TS5N118PWE4 is equipped with dual discharge networks for improved signal integrity. These networks help minimize signal distortion and enable high speed operation. The device also features a low voltage dropout (VDS), which helps to ensure low power consumption and reduce voltage drop caused by the power supply source.

Conclusion

TS5N118PWE4 is a versatile and reliable logic-signal switch that is widely used in multiplexers, decoders, and other electronic circuits. Its logic-signal switch design utilizes an insulated gate bipolar transistor (IGBT) and a p-channel MOSFET and includes a static protection diode and dual discharge networks for improved signal integrity. With its impressive features and reliable performance, TS5N118PWE4 is capable of quickly and reliably controlling the flow of a signal and switching in the logic signal range of 2V to 8V.
