Description and Introduction

PUSH-PULL FOUR CHANNEL DRIVER WITH DIODES The L293D is a quadruple high-current half-H driver manufactured by STMicroelectronics (STM). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (VCC):** 4.5V to 36V  
- **Output Current:** 600mA per channel (1.2A peak)  
- **Logic Supply Voltage (VSS):** 5V  
- **Input Voltage (VIH):** 2.3V to VSS  
- **Input Voltage (VIL):** -0.3V to 1.5V  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** 16-pin DIP, SOIC  

### **Descriptions:**  
- The L293D is designed to drive inductive loads (such as relays, solenoids, DC, and bipolar stepping motors).  
- It has built-in clamp diodes for inductive load protection.  
- Each driver is enabled by a separate input pin, allowing independent control.  

### **Features:**  
- **Quadruple Half-H Drivers:** Can drive two DC motors bidirectionally or one stepper motor.  
- **Wide Supply Voltage Range:** Supports motor voltage from 4.5V to 36V.  
- **Separate Logic Supply (VSS):** Allows interfacing with 5V microcontrollers.  
- **Thermal Shutdown:** Prevents damage from overheating.  
- **High-Noise Immunity Inputs:** Reduces false triggering.  
- **Internal ESD Protection:** Enhances reliability.  

This information is strictly based on the manufacturer's datasheet.
