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. NOTE 1: The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions (see Note 2) CY54FCT543T CY74FCT543T UNIT MIN NOM MAX MIN NOM MAX UNIT VCC Supply voltage 4.5 5 5.5 4.75 5 5.25 V VIH High-level input voltage 2 2 V VIL Low-level input voltage 0.8 0.8 V IOH High-level output current –12 –32 mA IOL Low-level output current 48 64 mA TA Operating free-air temperature –55 125 –40 85 °C NOTE 2: All unused inputs of the device must be held at VCC or GND to ensure proper device operation. |
