3 Description

The SN74LV1T126-Q1 is a single buffer gate with 3-

state outputs and integrated voltage translation. This

buffer performs the Boolean function Y = A in positive

logic. The outputs can be placed into a Hi-Z state by

applying a Low on the OE pin. 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). In addition, the 5-V tolerant input pins

enable down translation (for example, 3.3 V to 2.5 V

output).
