3 Description

The SN74LV4T125-Q1 contains four independent

buffers with 3-state outputs and extended voltage

operation to allow for level translation. Each buffer

performs the Boolean function Y = A in positive logic.

The outputs can be put into a high impedance (Hi-Z)

state by applying a HIGH 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).
