74LV1T126 Single supply translating buffer/line driver 3-state Rev. 2 3 December 2019 Product data sheet 1. General description The 74LV1T126 is a single, level translating buffer/line driver with 3-state output. The low threshold inputs support 1.8 V input logic at V = 3.3 V and can be used in 1.8 V to 3.3 V level up CC translation. In addition, the 5 V tolerant input pins enable down translation (3.3 V to 2.5 V output at V = 2.5 V). The 3-state output is controlled by the output enable input (OE). A LOW-level at CC OE causes the output to assume a high-impedance OFF-state. 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 V range CC permits the generation of output levels to connect to controllers or processors. 2.
