Working Principles

SN74LVC245ANSRG4 operates by receiving input signals from one voltage domain and translating them to the corresponding voltage level in another domain. The direction of translation is controlled by the DIR pin. When DIR is set to high, the IC translates signals from A1-A8 to B1-B8. Conversely, when DIR is low, the translation occurs in the opposite direction.
