Working Principles

The 74LVT245BD,118 is designed using LVT (Low-Voltage TTL) logic family. It operates by translating digital signals between two voltage domains. The direction of translation is controlled by the DIR (Direction) pin. When DIR is set to high, the IC acts as a level shifter, translating signals from A-side to B-side. Conversely, when DIR is low, it performs the opposite translation.

The OE (Output Enable) pin is used to enable or disable the outputs. When OE is high, the outputs are enabled, allowing bidirectional communication. When OE is low, the outputs are disabled, effectively isolating the two voltage domains.
