General description

   The 74LV1T34 is a single, level translating buffer. The low threshold inputs support 1.8 V input logic at VCC = 3.3 V and can be used in 1.8 V to 3.3 V level up translation. In addition, the 5 V tolerant input pins enable level down translation (3.3 V to 2.5 V output at VCC = 2.5 V). The output level is referenced to the supply voltage and supports 1.8 V, 2.5 V, 3.3 V and 5.0 V CMOS levels. The wide VCC range permits the generation of output levels to connect to controllers or processors.
