The SN74LV1T34-Q1 contains a single buffer with extended voltage operation to allow for level translation. The buffer performs the Boolean function Y = A in positive logic. 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).
