Description and Introduction

QUAD 2-INPUT AND GATE (OPEN DRAIN) The **M74HC09** is a quad 2-input AND gate integrated circuit (IC) manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Logic Family:** HC (High-Speed CMOS)  
- **Supply Voltage (VCC):** 2V to 6V  
- **High-Level Input Voltage (VIH):** 2V (min) at VCC = 4.5V  
- **Low-Level Input Voltage (VIL):** 0.8V (max) at VCC = 4.5V  
- **High-Level Output Current (IOH):** -5.2mA at VCC = 4.5V  
- **Low-Level Output Current (IOL):** 5.2mA at VCC = 4.5V  
- **Propagation Delay (tpd):** 10ns (typ) at VCC = 4.5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** SO-14, TSSOP-14  

### **Descriptions:**
- The **M74HC09** contains four independent **2-input AND gates** with **open-drain outputs**.  
- Open-drain outputs require an external pull-up resistor for proper logic-level operation.  
- Compatible with **TTL** levels when operated at 5V supply.  
- Suitable for **bus-oriented systems** and **wired-AND applications**.  

### **Features:**
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **High Noise Immunity:** Improved noise margins compared to standard CMOS.  
- **Balanced Propagation Delays:** Ensures reliable timing performance.  
- **Wide Operating Voltage Range:** Supports 2V to 6V operation.  
- **ESD Protection:** HBM (Human Body Model) ≥ 2000V.  

This IC is commonly used in digital logic circuits, signal processing, and microcontroller interfacing applications.
