6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Supply voltage, VCC –0.5 7 V
Input voltage, VI(2) –0.5 VCC + 0.5 V
Output voltage, VO(2) –0.5 VCC + 0.5 V
Input clamp current, IIK VI < 0 or VI > VCC ±20 mA
Output clamp current, IOK VO < 0 or VO > VCC ±20 mA
Continuous output current, IO VO = 0 to VCC ±25 mA
Continuous current through VCC or GND ±50 mA
Operating junction temperature, TJ 150 °C
Storage temperature, Tstg –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 and output voltage ratings may be exceeded if the input and output current ratings are observed.

6.2 ESD Ratings

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) ±1000
(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.

6.3 Recommended Operating Conditions

see(1)
MIN MAX UNIT
VCC Supply voltage 4.5 5.5 V
VI Input voltage 0 VCC V
VO Output voltage 0 VCC V
TA Operating free-air temperature SN54HCT14 –55 125 °C
SN74HCT14 –40 85
(1) All unused inputs of the device must be held at VCC or GND to ensure proper device operation. See the TI application report, Implications of Slow or Floating CMOS Inputs (SCBA004).
