Overview
The NLSX5014DR2G, produced by onsemi, is a 4-bit configurable dual-supply autosensing bidirectional level translator. This device does not require a direction control pin, allowing for flexible and efficient logic signal translation between two different power supply rails, VCC and VL. The VCC and VL supply rails can be configured from 0.9 V to 4.5 V, enabling the translation of logic signals from one voltage level to another without restrictions on the relative values of VCC and VL. This feature maximizes design flexibility, especially in systems with multiple supply voltages.
