The NLSX4378 is a 4−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 1.65 V to 5.5 V while VL supply rail is configurable to 1.65 V to 5.5 V. This allows voltage logic signals on the VL side to be translated into lower, higher or equal value voltage logic signals on the VCC side, and vice−versa.

FEATUREs
