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.
PRODUCT HIGHLIGHTS
1. Bidirectional level translation matches any voltage level
from 1.65 V to 3.6 V.
2. The bypass switch offers high performance and is fully
guaranteed across the supply range.
3. Short circuit protection.
4. Tiny 8-lead SOT-23 package and 8-lead MSOP.
