Description

The FXLA104 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

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 FXLA104 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.
