11 / 25 page SN74LV4T125 www.ti.com SCLS749B – FEBRUARY 2014 – REVISED SEPTEMBER 2014 9.3 Feature Description This part is a single supply buffer that is capable up or down translation. The output will equal VCC while the input can vary from 1.2 V to 5.5 V. Up Translation Mode: • 1.2 V to 1.8 V at 1.8-V VCC • 1.5 V to 2.5 V at 2.5-V VCC • 1.8 V to 3.3 V at 3.3-V VCC • 3.3 V to 5.0 V at 5.0-V VCC Down Translation Mode: • 3.3 V to 1.8 V at 1.8-V VCC • 3.3 V to 2.5 V at 2.5-V VCC • 5.0 V to 3.3 V at 3.3-V VCC 9.4 Device Functional Modes This device performs the function of a buffer where input logic level equals the output logic level, while providing buffering and drive to the output. The SN74LV4T125 device will also translate voltages up or down while performing this function. Table 1. Function Table (Each Buffer) INPUTS OUTPUT Y OE A L H H L L L H X Z Table 2.
