Description
The FXLA101 is a configurable dual-voltage supply
translator for both uni-directional and bi-directional
voltage translation between two logic levels. The device
allows translation between voltages as high as 3.6V to
as low as 1.1V. The A port tracks the V
B port tracks the V
voltage translation over a variety of voltage levels: 1.2V,
1.5V, 1.8V, 2.5V, and 3.3V.
The device remains in three-state as long as 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
ports by placing them in a 3-state condition. The /OE
input is supplied by V
The FXLA101 supports bi-directional translation without
the need for a direction control pin. The two ports 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.
