-## 2. Pin Configuration
30
-If you connect it like:
31
-- One diode goes from **Common → 3.3V**
32
-- Other diode goes from **Common → GND**
33
-
34
-It means:
35
-- **D1**: Cathode at 3.3V, Anode at Common
36
-- **D2**: Anode at GND, Cathode at Common
37
-
38
-So the common pin sits in the **middle** between **0V (GND)** and **3.3V (VCC)**, clamped by diodes.
39

40
----
41
-
42
-## 3. Purpose of This Setup
43
-This creates a **clamp/protection circuit**:
44
-- If the signal on the **Common pin** rises above **3.3V + Vf (~3.9V)** → the upper diode conducts → clamps to 3.3V rail.
45
-- If the signal falls below **0V – Vf (~–0.7V)** → the lower diode conducts → clamps to GND.
46
-
47
-👉 This is often used as an **ESD protection** or **logic level protection** for sensitive inputs.
