8.4 Device Functional Modes

The SN74AVC24T245 is a voltage level translator that can operate from 1.2 V to 3.6 V (VCCA) and 1.2 V to 3.6 V (VCCB). 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.
