The SN74LV8T245 is an octal bus transceiver with 3-state outputs. All eight channels are controlled by the direction (DIR) pin and output enable ( OE) pin. The output level is referenced to the supply voltage (V CC) and supports 1.8-V, 2.5-V, 3.3-V, and 5-V CMOS levels.

The input is designed with a lower threshold circuit to support up translation for lower voltage CMOS inputs (for example, 1.2 V input to 1.8 V output or 1.8 V input to 3.3 V output). Additionally, the 5-V tolerant input pins enable down translation (for example, 3.3 V to 2.5 V output).
