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 voltage ratings may be exceeded if the input and output current ratings are observed. 2. The maximum package power dissipation is calculated using a junction temperature of 150 _C and a board trace length of 750 mils. recommended operating conditions (see Note 3) 54ACT16952 74ACT16952 UNIT MIN NOM MAX MIN NOM MAX UNIT VCC Supply voltage 4.5 5 5.5 4.5 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 VO Output voltage 0 VCC 0 VCC V IOH High-level output current –24 –24 mA IOL Low-level output current 24 24 mA ∆t/∆v Input transition rise or fall rate 0 10 0 10 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.
