Description and Introduction

PUSH-PULL FOUR CHANNEL DRIVER WITH DIODES The L293DD is a motor driver IC manufactured by STMicroelectronics. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** STMicroelectronics  
- **Part Number:** L293DD  
- **Type:** Quadruple Half-H Driver  
- **Operating Voltage (VCC):** 4.5V to 36V  
- **Output Current (per channel):** 600mA (continuous), 1.2A (peak)  
- **Input Voltage (VIH):** 2.3V to 7V (TTL/CMOS compatible)  
- **Package:** SOIC-16  
- **Operating Temperature Range:** -40°C to +150°C  
- **Enable Function:** Yes (separate enable pins for each half-bridge)
