FXLA104 / FXLA108 Automatic Direction Translators

onsemi / Fairchild FXLA108 and FXLA104 are configurable automatic direction dual-voltage supply translators for both uni-directional and bi-directional voltage translation between two logic levels. The devices allow translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the V_CCA level 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 FXLA108 and FXLA104 remain 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.
