ISL43681IR-T is an integrated analog switch, multiplexer and demultiplexer chip developed and manufactured by Intersil Corporation. Its application fields include automotive, audio, video and industrial applications. It features wide bandwidth, low power consumption, low power requirements, low phase shift, high ESD performance and wide dynamic range.

The Analog switch, multiplexer and demultiplexer are devices used to select, connect or disconnect one or more input signals. It is mainly used for analog signal switching, multiplexing and demultiplexing applications. An analog switch is a device that can switch analog signals between several different inputs by controlling a single control signal. It is typically used in high speed applications such as RF communications. A multiplexer is a device that can accept several inputs simultaneously and select one at a time. A demultiplexer can accept one or two inputs and select outputs corresponding to these inputs.

ISL43681IR-T is a low power, wide bandwidth, high ESD tolerance and low phase shift multiplexer and demultiplexer. It has two groups of eight channels and four control inputs. The channels are designed to operate up to 400 MHz with a power supply of +5V. The ISL43681IR-T can also be used in fractional-N frequencies up to 3GHz. It features low on-resistance, low Off-state leakage current, low power, and low propagation delay. It is available in small 8-lead TSSOP, 8-lead SOIC, 8-lead VQFN, 8-lead MSOP, 8-lead TSSOPd, and 8-lead WLCSP packages.

ISL43681IR-T has a single-ended control signal, B0-B3, to control the switch states of eight channels simultaneously. The signal B0 is used to enable or disable all eight channels while signal B1 is used to select the channel to be enabled or disabled. When signal B1 is high all channels are enabled and when signal B1 is low all channels are disabled. Signal B2 and B3 can be used to select a single channel that needs to be enabled or disabled.

ISL43681IR-T offers low power consumption with typical power consumption of 700 uA when channel is enabled and less than 1uA when the channel is disabled. It also has low phase shift up to 400MHz, low Off-state leakage current, and high ESD performance. Its output characteristics are flat, linear, and wide dynamic range. It is suitable for wide range of applications such as RF signal routing, analog signal multiplexing, demultiplexing, power supply sequencing, telecom systems and audio/video applications.

In summary, ISL43681IR-T is a low power, wide bandwidth, low phase shift multiplexer and demultiplexer chip developed by Intersil Corporation. It features low on-resistance, low Off-state leakage current, low power consumption, and high ESD performance. It is suitable for wide range of applications such as RF signal routing, analog signal multiplexing, demultiplexing, power supply sequencing, telecom systems and audio/video applications.
