The FXMA108 is a configurable dual-voltage supply translator designed for both uni-directional and bidirectional 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 level. This allows for 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 Vs reach active levels, allowing either V to be powered-up first. Internal power-down control circuits place the device in 3-state if either V is removed. 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 Side 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.
