Overview
The NLSX5012MUTAG, produced by onsemi, is a 2-bit configurable dual-supply autosensing bidirectional level translator. This device does not require a direction control pin and is designed to translate logic signals between two different power supply rails, VCC and VL, which can range from 0.9 V to 4.5 V. The NLSX5012 offers flexibility in its operation, allowing VL to be set to a value greater than, equal to, or less than VCC, which is a significant advantage over many competitive auto-sense translators.
