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. This current flows only when the output is in the high state and VO > VCC. 3. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions (see Note 4) SN54LVTH374 SN74LVTH374 UNIT MIN MAX MIN MAX UNIT VCC Supply voltage 2.7 3.6 2.7 3.6 V VIH High-level input voltage 2 2 V VIL Low-level input voltage 0.8 0.8 V VI Input voltage 5.5 5.5 V IOH High-level output current −24 −32 mA IOL Low-level output current 48 64 mA ∆t/∆v Input transition rise or fall rate 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 4: All unused control inputs of the device must be held at VCC or GND to ensure proper device operation.
