The ADG3233 is a bypass switch designed on a submicron process which operates from supplies as low as1.65 V. The device is guaranteed for operation over the supply range 1.65 V to 3.6 V. It operates from two supplyvoltages allowing bidirectional level translation, that is. it translates low voltages to higher voltages and vice versa.The signal path is unidirectional, meaning 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 tobypassing devices in a JTAG chain or bypassing devices in a daisy-chain loop. One switch could be used for eachdevice or a number of devices, thus allowing easy bypassing of one or more devices in a chain. This may beparticularly useful in reducing the time overhead in testing devices in the JTAG chain or in daisy-chain applicationswhere 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-leadSOT-23 package requires only 2.9 mm x 2.8 mm board space, while the MSOP package occupies approximately3 mm x 4.9 mm board area.
