The NLSX4402 is a 2−bit configurable dual−supply bidirectionalauto sensing translator that does not require a directional control pin.The VCC I/O and VL I/O ports are designed to track two differentpower supply rails, VCC and VL respectively. Both the VCC and VLsupply rails are configurable from 1.5 V to 5.5 V. This allows voltagelogic signals on the VL side to be translated into lower, higher orequal value voltage logic signals on the VCC side, and vice−versa.The NLSX4402 translator uses external pull−up resistors on theI/O lines. The external pull−up resistors are used to pull up the I/Olines to either VL or VCC. The NLSX4402 is an excellent match foropen−drain applications such as the I2C communication bus.
