9.4 Device Functional Modes
The SN74AVCH16T245 is a voltage level translator that can operate from 1.2 V to 3.6 V (V_CCA) and 1.2 V to 3.6
V (V_CCB). The signal translation between 1.2 V and 3.6 V requires direction control and output enable control.
When OE is low and DIR is high, data transmission is from A to B. When OE is low and DIR is low, data
transmission is from B to A. When OE is high, both output ports will be high-impedance.
