SN74LV1T34 - Single Power Supply BUFFER Logic Level Shifter (no enable)

The SN74LV1T34 device is a low voltage CMOS gate logic that operates at a wider voltagerange for industrial, portable, and telecom applications. The output level is referenced to thesupply voltage and is able to support 1.8-V, 2.5-V, 3.3-V, and 5-V CMOS levels.

The input is designed with a lower threshold circuit to match 1.8 V input logic atV_CC = 3.3 V and can be used in 1.8 V to 3.3 V level up translation. Inaddition, the 5 V tolerant input pins enable down translation (that is, 3.3 V to 2.5 V output atV_CC = 2.5 V). The wide V_CC range of 1.8 V to 5.5 Vallows generation of desired output levels to connect to controllers or processors.

The SN74LV1T34 device is designed with current-drive capability of 8 mA to reduce linereflections, overshoot, and undershoot caused by high-drive outputs.
