The FXL4T245 is a configurable dual-voltage-supply translator designed for bi-directional voltage translation of signals between two voltage levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A Port tracks the V level, and the B Port tracks the V level. Both ports are designed to accept supply voltage levels from 1.1V to 3.6V. 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 Vs reach active levels allowing either V to be powered-up first. The device also contains power down control circuits that place the device in 3-STATE if either VThe Transmit/Receive (T/R#) input determines the direction of data flow through the device. The OE# input, when HIGH, disables both the A and B Ports by placing them in 3-STATE condition. The FXL4T245 is designed so that the control pins (T/R# and OE#) are supplied by V
