1. General description

The 74LV1T34-Q100 is a single, level translating buffer. The low threshold inputs support 1.8 V

input logic at VCC = 3.3 V and can be used in 1.8 V to 3.3 V level up translation. In addition, the 5 V

tolerant input pins enable level down translation (3.3 V to 2.5 V output at VCC = 2.5 V). The output

level is referenced to the supply voltage and supports 1.8 V, 2.5 V, 3.3 V and 5.0 V CMOS levels.

The wide VCC range permits the generation of output levels to connect to controllers or processors.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
