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 V_CC = 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 V_CC = 2.5V). The wide V_CC
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.
