SN74LV1T125DCKR Description

For industrial, portable, telecom, and automotive applications, the SN74LV1T125DCKR is a low voltage CMOS gate logic that operates across a larger voltage range. The output level is related to the supply voltage and can accommodate CMOS levels of 1.8V/2.5V/3.3V/5V.

The input is built with a lower threshold circuit to match 1.8V input logic at VCC = 3.3V and can be used in level up translation from 1.8V to 3.3V. Down translation (e.g. 3.3V to 2.5V output at VCC = 2.5V) is also possible thanks to the 5V tolerant input pins. The VCC range of 1.8V to 5.5V allows for the production of desired output levels for controllers or processors.

To prevent line reflections, overshoot, and undershoot produced by high-drive outputs, the SN74LV1T125DCKR is designed with a current-drive capability of 8 mA.

What is single buffer gate?

The Single Buffer Gate is a low voltage CMOS gate logic that operates at a wider voltage range for industrial, portable, telecom, and automotive applications.

What is buffer gate?

The Buffer Gate is a logic block that takes any input and compares the value to 0. If the input signal is zero, the output will be zero. If the input is non-zero, the output will be a “1” in the bit position designated by the drop-down box.
