Description
The
FXMA2104
is
a
4-bit
high-performance,
configurable dual-voltage supply, open-drain translator
for bi-directional voltage translation over a wide range of
input and output voltages levels.
Intended for use as a voltage translator in applications
using the I
2C-Bus® interface, the input and output
voltage
levels
are
compatible
with
I
2C device
specification voltage levels. External pull-up resistors
are required.
The device is designed so that the A port tracks the
VCCA level and the B port tracks the VCCB level. This
allows for bi-directional A/B port voltage translation
between any two levels from 1.65V to 5.5V. VCCA can
equal VCCB from 1.65V to 5.5V.
Non-preferential power-up means either VCC can be
powered-up first. Internal power-down control circuits
place the device in 3-state if either VCC is removed.
The two ports of the device have automatic direction-
sense capability. Either port may sense an input signal
and transfer it as an output signal to the other port.
