SN74LV1T34/SN74LV1T34-Q1 Logic Level Shifter Texas Instruments SN74LV1T34/SN74LV1T34-Q1 Buffer Logic Level Shifter is a low-voltage CMOS gate logic that operates at a wider voltage range for industrial, portable, and telecom 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 generating desired output levels to connect to controllers or processors. The SN74LV1T34-Q1 devices are AEC-Q100 qualified for automotive applications.
