SN74LV4T125 is a low-voltage CMOS buffer gate that operates at a wider voltage range for portable, telecom, industrial, and automotive applications. The output level is referenced to the supply voltage and is able to support 1.8-V, 2.5-V, 3.3-V, and 5-V CMOS levels.
The input is designed with a lower threshold circuit to match 1.8-V input logic at VCC = 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 (for example, 3.3 V to 2.5 V output at VCC = 2.5 V). The wide VCC range of 1.8 V to 5.5 V allows the generation of desired output levels to connect to controllers or processors.
The SN74LV4T125 device is designed with current-drive capability of 8 mA to reduce line reflections, overshoot, and undershoot caused by high-drive outputs.
