The FXLH42245MPX is a configurable 8-bit, dual-voltage-supply translator designed for bi-directional signal translation between two distinct voltage levels from 1.1V to 3.6V. The A port tracks the VCCA supply and the B port tracks the VCCB supply, supporting translation between common levels like 1.2V, 1.8V, 2.5V, and 3.3V. Key features include a transmit/receive (T/R) input to control data direction, an output enable (OE) pin, Bushold data inputs to eliminate external resistors, and 26Ω series resistors on the B-port outputs to reduce line noise. The device offers power-off protection and allows for non-preferential power-up sequencing, making it ideal for mixed-voltage system designs requiring robust level shifting and signal integrity.
