3 Description

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 (VCC) 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).
