General Description
The FXLA102 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 3.6V to as low as 1.1V. The A port tracks the VCCA level, and the B port tracks the VCCB 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 3-state until both VCCs reach active levels, allowing either VCC to be powered-up first. Internal power down control circuits place the device in 3-state if either VCC 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 VCCA. The FXLA102 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.
