3 Description
The SN74LV1T34 device 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 1.8-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 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 down translation
(that is, 3.3 V to 2.5 V output at VCC = 2.5 V). The
wide VCC range of 1.8 V to 5.5 V allows generation of
desired output levels to connect to controllers or
processors.
The SN74LV1T34 device is designed with currentdrive capability of 8 mA to reduce line reflections,
overshoot, and undershoot caused by high-drive
outputs.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
The input negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
