74LV1T126
Single supply translating buffer/line driver; 3-state
Rev. 1 — 28 November 2017
Product data sheet

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
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 LOW-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.

If the input current ratings are observed, the minimum input voltage ratings may be exceeded.
If the output current ratings are observed, the output voltage ratings may be exceeded.
This value is limited to 7 V maximum.
For TSSOP5 packages: above 75 °C the value of P
tot
derates linearly with 3.3 mW/K.
For X2SON5 package: above 70 °C the value of P
tot
derates linearly with 3.1 mW/K.
