Interpreting the SN51DP Datasheet
- Function: Converts between RS-232 (±3 to ±15 V) signaling levels and TTL/CMOS logic levels (commonly 3.3 V or 5 V). Often integrates charge-pump voltage generation so it can create the negative RS-232 voltages from a single supply.
- Typical uses: Serial ports on embedded systems, microcontroller UART interfacing, legacy device connectivity, modem and serial peripheral links.
This is the most popular application. Connect the relay coil between V+ (e.g., 24V) and the output pin. Connect the COM pin to the same V+. The internal diode will clamp inductive kickback.

- Input/output capacitors: Specified by type (e.g., X5R/X7R ceramic) and value.
- Inductor: Recommended inductance (e.g., 10µH) and saturation current rating.
- Feedback resistors: Calculated to set V_OUT = V_REF * (1 + R1/R2).
- Bootstrap capacitor (C_BST): Essential for high-side gate drive.
