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. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51. recommended operating conditions (see Note 3) SN54ABT16623 SN74ABT16623 UNIT MIN MAX MIN MAX UNIT VCC Supply voltage 4.5 5.5 4.5 5.5 V VIH High-level input voltage 2 2 V VIL Low-level input voltage 0.8 0.8 V VI Input voltage 0 VCC 0 VCC V IOH High-level output current –24 –32 mA IOL Low-level output current 48 64 mA ∆t/∆v Input transition rise or fall rate Outputs enabled 5 5 ns/V TA Operating free-air temperature –55 125 –40 85 °C NOTE 3: Unused pins (input or I/O) must be held high or low to prevent them from floating.
