3 Description
SN74LV1T126 is a low voltage CMOS gate logic that
operates at a wider voltage range for industrial,
portable, telecom, and automotive applications. The
output level is referenced to the supply voltage and is
able to support 1.8V/2.5V/3.3V/5V CMOS levels.
The input is designed with a lower threshold circuit to
match 1.8V input logic at VCC = 3.3V and can be used
in 1.8V to 3.3V level up translation. In addition, the
5V tolerant input pins enable down translation (e.g.
3.3V to 2.5V output at VCC = 2.5V). The wide VCC
range of 1.8V to 5.5V allows generation of desired
output levels to connect to controllers or processors.
The SN74LV1T126 is designed with current-drive
capability of 8 mA to reduce line reflections,
overshoot, and undershoot caused by high-drive
outputs.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
The package thermal impedance is calculated in accordance with JESD 51-7.
