## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Improper Pull-Up Resistor Selection
- Problem : Incorrect resistor values causing slow rise times or excessive power consumption
- Solution : Calculate optimal values based on required rise time and power budget
- Fast switching: 1kΩ to 4.7kΩ
- Power-sensitive: 10kΩ to 100kΩ
Pitfall 2: Voltage Domain Mismatch
- Problem : Input voltages exceeding VCC causing latch-up or damage
- Solution : Implement voltage clamping or series resistors when interfacing with higher voltage signals
Pitfall 3: Insufficient Decoupling
- Problem : Power supply noise causing erratic behavior
- Solution : Place 100nF ceramic capacitor within 5mm of VCC pin
Pitfall 4: Signal Integrity Issues
- Problem : Ringing and overshoot in high-speed applications
- Solution : Implement series termination resistors (22Ω to 100Ω) near driver output
