Low Voltage 1.65 V to 3.6 V, (Up/Down) Logic Level Translation, Bypass Switch
The ADG3233 is a bypass switch designed on a submicron 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 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 to bypassing devices in a JTAG chain or bypassing devices in a daisy-chain 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 SOT-23 package requires only 2.9 mm x 2.8 mm board space, while the MSOP package occupies approximately 3 mm x 4.9 mm board area.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The EVAL-8MSOPEBZ is the evaluation board for the 8 lead MSOP devices in the switch/mux portfolio which are to be purchased separately. A clamp is supplied with the board so that the device can be secured to the board without the need for soldering. This makes the board reusable for multiple devices.
The device can be clamped or soldered to the center of the evaluation board. Each pin of the device is broke out to a link that can be set to either VDD or GND and a wire screw terminal is provided to supply VDD and GND. SMB connectors are on the board allow for additional external signals to be supplied to the device. In addition, there is space at the top of the board available for prototyping.
Full specifications of the device under test are available in the product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.
