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_CCAlevel and the B port tracks the V_CCB level. This allows for bi-directional 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 until both V_CCs reach active levels, allowing either V_CC to be powered up first. Internal power-down control circuits place the device in 3-state if either V_CC is removed.

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_CCA.

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.
