operation.
The ’LV14 devices contain six independent
inverters. These devices perform the Boolean
function Y = A.
The SN54LV14 is characterized for operation over
the full military temperature range of –55°C to
125°C. The SN74LV14 is characterized for
operation from –40°C to 85°C.

‡ Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stressratings 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.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. This value is limited to 7 V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51.
