The ADG3233 is a bypass switch designed on a sub micron process which operates from supplies as low as 1.65 V. The device is guaranteed for operation over the supply range 1.65 V to 3.6 V. It operates from two supply voltages allowing bi-directional level translation, i.e. it translates low voltages to higher voltages and vice versa. The signal path is uni-directional, data may only flow from A to Y.
This type of device may be used in applications that require a bypassing function. It is ideally suited to bypassing devices in a JTAG chain or bypassing devices in a daisychain loop. One switch could be used for each device or a number of devices thus allowing easy bypassing of one or more devices in a chain. This may be particularly useful in reducing the time overhead in testing devices in the JTAG chain or in daisy chain applications where the user does not wish to change the settings of a particular device.The Bypass Switch is packaged in two of the smallest footprints available for its required pin count. The 8 lead SOT23 package requires only 8.26mm2 board space, while the MicroSOIC package occupies approximately 15mm2 board area.

Bus Switches for Speed, Safety, and Efficiency: What They Are and What You Should Know About Them.
Bus switches are characterized by sub-nanosecond propagation delay and fast switching, and are designed for connecting to high-speed digital buses. They are ideally suited for voltage translation, hot swapping, hot plug, bus- or capacitance isolation, and many other applications. The key features that make them suitable for so many different applications include low on-resistance, low capacitance, and low propagation delay.
