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 JESD 51. recommended operating conditions, VCC = 2.5 V ± 0.2 V (see Note 3) SN54ALVTH162827 SN74ALVTH162827 UNIT MIN TYP MAX MIN TYP MAX UNIT VCC Supply voltage 2.3 2.7 2.3 2.7 V VIH High-level input voltage 1.7 1.7 V VIL Low-level input voltage 0.7 0.7 V VI Input voltage 0 VCC 5.5 0 VCC 5.5 V IOH High-level output current –6 –8 mA IOL Low-level output current 8 12 mA ∆t/∆v Input transition rise or fall rate Outputs enabled 10 10 ns/V ∆t/∆VCC Power-up ramp rate 200 200 µs/V TA Operating free-air temperature –55 125 –40 85 °C NOTE 3: All unused control inputs of the device must be held at VCC or GND to ensure proper device operation.
