GENERAL DESCRIPTION

The ADG32331 is a bypass switch designed on a submicron

process that 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 → 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 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 × 2.8 mm board space, while the MSOP

package occupies approximately 3 mm × 4.9 mm board area.
