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 voltage ratings may be exceeded if the input and output current ratings are observed. 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VCC Supply voltage –0.5 7 V IIK Input clamp current(2) VI < 0 or VI > VCC ±20 mA IOK Output clamp current(2) VO < 0 or VO > VCC ±20 mA IO Continuous output current VO = 0 to VCC ±25 mA Continuous current through VCC or GND ±50 mA TJ Junction temperature 150 °C Tstg Storage temperature –65 150 °C (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions. 6.2 ESD Ratings – SN74HC273 VALUE UNIT V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±500 (1) All unused inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) (1) MIN NOM MAX UNIT VCC Supply voltage 2 5 6 V VIH High-level input voltage VCC = 2 V 1.5 V VCC = 4.5 V 3.15 VCC = 6 V 4.2 VIL Low-level input voltage VCC = 2 V 0.5 V VCC = 4.5 V 1.35 VCC = 6 V 1.8 VI Input voltage 0 VCC V VO Output voltage 0 VCC V ∆t/∆v Input transition rise and fall time VCC = 2 V 1000 ns VCC = 4.5 V 500 VCC = 6 V 400 TA Operating free-air temperature SN54HC273 –55 125 °C SN74HC273 –40 85 |
