Description and Introduction

PUSH-PULL FOUR CHANNEL DRIVERS The L293E is a quad push-pull driver manufactured by STMicroelectronics (STM). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Current:** 1A per channel (peak current up to 2A)  
- **Supply Voltage (VCC):** 4.5V to 36V  
- **Logic Supply Voltage (VSS):** 5V (supports TTL & CMOS levels)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Number of Channels:** 4 (quad half-H-bridge)  
- **Output Configuration:** Push-pull  
- **Package:** PowerDIP16  

### **Descriptions:**  
- The L293E is designed to drive inductive loads (such as relays, solenoids, DC, and bipolar stepping motors).  
- It incorporates four independent half-H-bridge drivers, allowing bidirectional control of two DC motors or a single stepper motor.  
- Features built-in flyback diodes for inductive load protection.  
- Compatible with TTL and CMOS logic levels for easy interfacing with microcontrollers.  

### **Features:**  
- **High-Voltage, High-Current Outputs** (up to 36V, 1A continuous per channel).  
- **Thermal Shutdown Protection** to prevent overheating.  
- **Internal Clamp Diodes** for inductive transient suppression.  
- **Separate Logic & Power Grounds** for noise reduction.  
- **Enable Inputs** for each channel to control motor direction and speed via PWM.  

This information is sourced from the manufacturer's datasheet and technical documentation.
