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.
