ISL84780IRZ is an analog switch and multiplexer integrated circuit (IC) developed by Intersil Corporation to switch signals from one source to another. The IC functions as both a multiplexer and demultiplexer, allowing it to be used in a variety of applications. The ISL84780IRZ is particularly well suited for applications requiring multiple inputs, which can range from simple circuit-switching functions to complex data routing operations. The ISL84780IRZ is aimed at a range of applications, including power management applications, audio and video signal compression and home and automotive audio systems.

The ISL84780IRZ is a 4-channel analog switch with an integrated multiplexer and demultiplexer. The switch can operate in three modes: single-pole double-throw (SPDT), dual-pole single-throw (DPST) and dual-pole double-throw (DPDT). The switch provides a low-power electrical interface with high linearity and low channel-to-channel crosstalk, enabling it to be used in applications with stringent signal-integrity requirements. The SPST mode is suitable for single-input/single-output applications, while the DPDT mode is suitable for dual-input/dual-output applications. The ISL84780IRZ has a low capacitance and low propagation delay, making it well suited for high-speed signals. It is also capable of handling signals up to 20V. Additionally, the switch offers low power consumption, making it well suited for battery-powered systems.

The ISL84780IRZ is configured with two logic pins, which are used to control the state of the switch. In the logic pins, a ‘1’ sets the switch to the ON position, while a ‘0’ sets the switch to the OFF position. The switch can also be configured to operate with an alternative control signal, such as a pulse-width modulation or digital-to-analog conversion. Additionally, the switch allows two independent controls to be used to operate two different channels.The control logic is TTL compatible and the device can be driven using digital logic.

The ISL84780IRZ is designed to be used in a number of applications. It is commonly used in audio and video systems, where the switch is used to switch between multiple audio and video streams. It is ideal for power management applications, where it can be used to switch between battery backup supplies and primary power supplies. The switch can also be used in automotive and home audio systems, where it is used to route multiple audio signals to different speakers. Additionally, the ISL84780IRZ is suitable for use in switched-mode power supplies, where it is used to switch between different voltage supplies.

The ISL84780IRZ is an analog switch and multiplexer IC with a wide range of applications. It is designed to switch signals from one source to another, while offering low power consumption, high linearity and low channel-to-channel crosstalk. The two logic pins are used to control the state of the switch, while an alternative control signal such as a pulse-width modulation can also be used. The ISL84780IRZ is suitable for applications such as audio and video switching, power management, automotive audio, home audio and switched-mode power supplies.
