Description
The FXMA108 is a configurable dual-voltage supply
translator designed for both uni-directional and bi-
directional voltage translation between two logic levels.
The device allows translation between voltages as high
as 5.5V to as low as 1.65V. The A port tracks the V
level and the B port tracks the V
bi-directional voltage translation over a variety of
voltage levels: 1.8V, 2.5V, 3.3V, and 5.0V.
The device remains in 3-state until both V
active levels, allowing either V
Internal power-down control circuits place the device in
3-state if either V
The /OE input, when high, disables both the A and B
Side by placing them in a 3-state condition. The /OE
input is supplied by V
The FXMA108 supports bi-directional translation without
the need for a direction control pin. The two sides of the
device have auto-direction-sense capability. Either port
may sense an input signal and transfer it as an output
signal to the other port.
Applications
Cell Phones, PDA, Digital Camera, Portable GPS,
and Storage
