Low Voltage Dual Supply 8-Bit Signal Translator with Configurable Voltage Supplies and Bushold Data Inputs and 3-STATE and 26 Ohm Series Resistors in the B Port Outputs

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 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 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 with the control pins (T/R and OE) supplied by V_CCA.
