PRODUCTION DATA
The SN74LVC8T245-Q1 is voltage level translator that can operate from 1.65 V to 5.5 V (VCCA and VCCB). The signal translation between 1.65 V and 5.5 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. For voltage level translation below 1.65V, see TI AXC products.
