Description and Introduction

One microamp supply-current, +3V to +5.5V, 250kbps, RS-232 transmitter/receiver The ICL3232CA is a dual-channel RS-232 transceiver manufactured by **Intersil** (now part of Renesas Electronics). Below are the key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to **250 kbps**  
- **Operating Temperature Range:** **0°C to 70°C** (Commercial grade)  
- **Number of Drivers/Receivers:** **2 Drivers, 2 Receivers**  
- **ESD Protection:** **±15kV (Human Body Model)** on transmitter outputs and receiver inputs  
- **Package:** **16-pin SOIC (Small Outline Integrated Circuit)**  

### **Descriptions:**  
- The ICL3232CA is a **3V to 5.5V-powered RS-232 transceiver** compliant with **EIA/TIA-232-F** standards.  
- It is designed for **serial data communication** in applications such as **PCs, industrial systems, and embedded devices**.  
- The device includes **on-board charge-pump circuitry**, eliminating the need for external ±12V power supplies.  

### **Features:**  
- **Low Power Consumption:** Operates from a **single 3V to 5.5V supply**.  
- **Auto-Powerdown Feature:** Reduces power consumption when not in use.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to **±15kV**.  
- **Meets EIA/TIA-232-F Standards:** Ensures compatibility with RS-232 communication protocols.  
- **Small Footprint:** Available in a **16-pin SOIC package** for space-constrained applications.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

One microamp supply-current, +3V to +5.5V, 250kbps, RS-232 transmitter/receiver

Alternative Part Number

  • MAX3232CAE+ --: Pin-compatible RS-232 transceiver with the same 3V to 5.5V supply range and dual charge-pump design; widely available and a direct functional drop-in for the ICL3232CA.
  • SP3232ECA-L --: Equivalent 3V RS-232 transceiver in a similar SSOP package with matching driver/receiver count and charge-pump architecture, suitable as a drop-in replacement.
  • ST3232CDR --: Low-power 3V to 5.5V RS-232 transceiver with two drivers and two receivers, functionally equivalent and commonly used as an alternative to the ICL3232 series.
