FXLH42245 General Description

The FXLH42245 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_CCA level, and the B Port tracks the V_CCB level. Both ports are designed to accept supply voltage levels from 1.1V to 3.6V. This allows for bidirectional 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 V_CCs reach active levels allowing either V_CC to be powered-up first.The device also contains power down control circuits that place the device in 3-STATE if either V_CC is removed.

The 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 a 3-STATE condition. The FXLH42245 is designed so that the control pins (T/R and OE) are supplied by V_CCA.
