Working Principles

The S74LCX16244DTR2G is a logic level translator designed to enable communication between integrated circuits operating at different voltage levels. It utilizes a bidirectional architecture, allowing data to be translated from one voltage domain to another. The device features tri-state outputs, which can be disabled to effectively isolate the input and output sides.

The IC operates by detecting the logic levels on its input pins and translating them to the corresponding levels on the output pins. The translation is performed using a combination of level-shifting circuitry and voltage level detection. The device is designed to operate within a specified supply voltage range, ensuring reliable and accurate level translation.
