NLSX4373 2-Bit 20 Mb/s Dual-Supply Level Translator The NLSX4373 is a 2 bit configurable dual supply bidirectional auto sensing translator that does not require a directional control pin.
The VCC I/O and VL I/O ports are designed to track two different power supply rails, VCC and VL respectively.
The VCC supply rail is configurable from 1.5 V to 5.5 V while VL supply rail is configurable to 1.5 V to 5.5 V.
This allows voltage logic signals on the VL side to be translated into low
