Input Signals:
- Apply binary inputs to A₀, A₁, A₂, A₃ and B₀, B₁, B₂, B₃.
- Apply the carry input (C₀) as needed.
Output Signals:
- The sum outputs (S₀, S₁, S₂, S₃) will provide the result of the addition.
- The carry output (C₄) indicates if there is a carry out from the most significant bit.
Propagation Delay:
- Ensure that the propagation delay time (t_pd) is considered in the timing design of your circuit.
Operating Conditions:
- Ensure that the operating temperature and power dissipation limits are not exceeded.
Storage:
- Store the device in a dry, cool place within the specified storage temperature range to prevent damage.
