Description
The PI4ULS3V304 is a 4-bit configurable dual-supply
autosensing bidirectional level translator that does not
require a direction control pin. The B and A ports are
designed to track two different power supply rails,
VCCB and VCCA respectively.
The PI4ULS3V304 offers the feature that the values of
the VCCB and VCCA supplies are independent.
Design flexibility is maximized because VCCA can be
set to a value either greater than or less than the VCCB
supply.
The PI4ULS3V304 has high output current capability,
which allows the translator to drive high capacitive loads
such as most high frequency EMI filters. Another feature
of the PI4ULS3V304 is that each An and Bn channel
can function as either an input or an output.
An Output Enable (EN) input is available to reduce the
power consumption. The EN pin can be used to disable
both I/O ports by putting them in 3-state which
significantly reduces the supply current.
The PI4ULS3V304 is 2 kV System-Level ESD Capable.
