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. (2) The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed. (3) The value of VCC is provided in the recommended operating conditions table. (4) The package thermal impedance is calculated in accordance with JESD 51-7. 2 Submit Documentation Feedback Copyright © 2003–2008, Texas Instruments Incorporated Product Folder Link(s): SN74LVC257A-Q1 |
