5 / 30 page SN54LVC257A, SN74LVC257A www.ti.com SCAS294O – JANUARY 1993 – REVISED JUNE 2015 7 Specifications 7.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VCC Supply voltage –0.5 6.5 V VI Input voltage(2) –0.5 6.5 V VO Output voltage(2) (3) –0.5 VCC + 0.5 V IIK Input clamp current VI < 0 –50 mA IOK Output clamp current VO < 0 –50 mA IO Continuous output current ±50 mA Continuous current through VCC or GND ±100 mA Tstg Storage temperature –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The input negative-voltage and output 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. 7.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 Electrostatic V(ESD) V Charged-device model (CDM), per JEDEC specification JESD22-C101, all discharge ±1000 pins(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
