These are stressratings 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. This value is limited to 7 V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51. recommended operating conditions (see Note 4) SN54LV14 SN74LV14 UNIT MIN MAX MIN MAX UNIT VCC Supply voltage 2.7 5.5 2.7 5.5 V VIH High level input voltage VCC = 2.7 V to 3.6 V 2.4 2.4 V VIH High-level input voltage VCC = 4.5 V to 5.5 V 3.55 3.55 V VIL Low level input voltage VCC = 2.7 V to 3.6 V 0.4 0.4 V VIL Low-level input voltage VCC = 4.5 V to 5.5 V 1.25 1.25 V VI Input voltage 0 VCC 0 VCC V VO Output voltage 0 VCC 0 VCC V IOH High level output current VCC = 2.7 V to 3.6 V –6 –6 mA IOH High-level output current VCC = 4.5 V to 5.5 V –12 –12 mA IOL Low level output current VCC = 2.7 V to 3.6 V 6 6 mA IOL Low-level output current VCC = 4.5 V to 5.5 V 12 12 mA TA Operating free-air temperature –55 125 –40 85 °C NOTE 4: All unused inputs of the device must be held at VCC or GND to ensure proper device operation.
