FXLH1T45L6X

The FXLH1T45 is a single bit configurable dual−voltage supply translator designed for both uni−directional and bi−directional voltage translation between two logic levels. The device allows translation between voltages as high as 3.6 V to as low as 1.1 V. 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: 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V. 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 Transmit/Receive (T/R(overline)) input determines the direction of data flow through the device. The FXLH1T45 is designed so that the control pin (T/R(overline)) is supplied by VCCA.
