️· Manufacturer: Nexperia

2. Electrical Characteristics (Key Values - Summarized from Various Tables)

️· Supply Voltage (VCC):
- Not explicitly stated, but implied to be within a range (e.g., 2.0V to 6.0V) from the test data and calculations.
️· Input/Output Voltages: Specific test points use 0.1VCC, 0.5VCC, 0.9VCC and 1.3V.
️· Propagation Delay (tpd): (VCC = 4.5V) - These are just a few examples; refer to tables for a full range of values.
- 1In to nY: 20-34 ns
- Sn to nY: 14-27 ns
- nE to nY: 14-27 ns
️· High to Low Propagation Delay (tPHL): (VCC = 4.5V)
- 1In to nY: 19-34 ns
️· Low to High Propagation Delay (tPLH): (VCC = 4.5V)
- 1In to nY: 13-24 ns
️· Transition Time (tt): (VCC = 4.5V)
- 7-15 ns
️· Power Dissipation Capacitance (CPD): ~30 pF (dependent on testing conditions and input voltage)

3. Testing Conditions

️· Input Rise/Fall Time (tr, tf): 6.0 ns
️· Load Capacitance (CL): 15 pF, 50 pF (used for some measurements)

4. Important Notes & Formulas

️· Dynamic Power Dissipation (PD): A formula is provided to calculate this, which is relevant for power consumption analysis.
- `P D = C PD x V CC x f i x N + ∑(C L x V CC x f o )`
- Where:
■ `f i`: input frequency in MHz
■ `f o`: output frequency in MHz
■ `C L`: output load capacitance in pF
■ `N`: number of inputs switching
