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 package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions (see Note 3) SN54AHCT594 SN74AHCT594 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 5.5 0 5.5 V VO Output voltage 0 VCC 0 VCC V IOH High-level output current −8 −8 mA IOL Low-level output current 8 8 mA Dt/Dv Input transition rise or fall rate 20 20 ns/V TA Operating free-air temperature −55 125 −40 85 °C NOTE 3: All unused inputs of the device must be held at VCC or GND to ensure proper device operation.
