ISL43122IH-T is an integrated analogue switch and multiplexer/demultiplexer (MUX/DeMUX) IC which comes in an 8 pin TSSOP package. It is a dual SPDT analogue switches and single on-board DeMUX. It features low on-resistance, low power consumption and fast switching speed. It is suitable for product applications that require a combination of high voltage and low current.

The ISL43122IH-T multiplexer/demultiplexer has one on-board SPDT switch, two SPDT switches and one DeMUX. It can switch individual analogue channels from one bus to another. It can be used to route either one or two channels from one input to two or more outputs. The ISL43122IH-T nominal on-state resistance is less than 2 Ohms with a maximum DC voltage rating of ± 6V.

The ISL43122IH-T can be used in applications where a high degree of isolation is needed between input and output signals. It provides a low power analogue switch that can handle a wide variety of signals and is ideal for use in audio systems, multi-channels audio and microphone systems. It can also be used in medical instrumentation systems, automation systems and in automotive applications.

The working principle of the ISL43122IH-T is simple. It has two SPDT switches which can be activated by the logic signals. The activate state of the switches is determined by the logic signals present at the control pins. When the logic low is present at one of the control pins, the associated SPDT switch is activated and it allows the signal to pass from one input to one or more outputs. The on-board DeMUX can be activated by the logic signals. When the logic high is present at one of the control pins, the DeMUX is activated and the signal can be routed from one input to two or more outputs.

In summary, ISL43122IH-T is a dual SPDT analogue switch and single DeMUX IC which is suitable for applications that require high voltage and low current. It provides a low power analogue switch that can handle a wide variety of signals and is ideal for use in audio systems, multi-channel audio and microphone systems, medical instrumentation systems, automation systems and in automotive applications.
