74LV1T125
Single supply translating buffer/line driver; 3-state
Rev. 1 — 22 November 2017 Product data sheet
1 General description
The 74LV1T125 is a single, level translating buffer/line driver with 3-state output. The
low threshold inputs support 1.8 V input logic at V
CC
= 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 down translation
(3.3 V to 2.5 V output at V
CC
= 2.5 V). The 3-state output is controlled by the output
enable input (OE). A HIGH-level at 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
CC
range permits the generation of output
levels to connect to controllers or processors.
