SN74LV1T126 (ACTIVE)

Single Power Supply, Single BUFFER GATE w/ 3-State Output (active high enable)

 

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.
