Description and Introduction

DTMF/PULSE Switchable Dialer The LC7367 is a CMOS LSI (Large Scale Integration) integrated circuit designed for remote control transmitter applications. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Supply Voltage (VDD):** 2.2V to 5.5V  
- **Operating Temperature Range:** -20°C to +75°C  
- **Oscillation Frequency:** 455kHz (typical, when paired with a ceramic resonator)  
- **Output Type:** Open-drain output for remote control signals  
- **Package Type:** SOP (Small Outline Package) or similar  

### **Descriptions:**  
- The LC7367 is a remote control encoder IC used in infrared (IR) or RF remote control systems.  
- It generates modulated signals for transmitting commands to compatible receivers.  
- The IC includes a built-in oscillator circuit, requiring only an external resonator (typically 455kHz).  
- It supports multiple key inputs for different command functions.  

### **Features:**  
- **Low Power Consumption:** Suitable for battery-operated devices.  
- **Built-in Oscillator:** Reduces external component count.  
- **Custom Code Functionality:** Allows unique identification for different remote controls.  
- **Multiple Key Inputs:** Supports matrix or direct key inputs.  
- **Open-Drain Output:** Compatible with IR LED or RF modulation circuits.  

This information is based on the LC7367's typical datasheet and application notes. For exact details, refer to the manufacturer's documentation.
