Description and Introduction

DUAL 4 CHANNEL MULTIPLEXER 3 STATE OUTPUT The M74HC253M1R is a dual 4-input multiplexer with 3-state outputs, manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Logic Family:** HC (High-speed CMOS)  
- **Number of Circuits:** 2  
- **Number of Inputs per Multiplexer:** 4  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package Type:** SO-16  

### **Descriptions:**  
- The M74HC253M1R consists of two independent 4-input multiplexers with common select inputs (S0, S1).  
- Each multiplexer has an active-low output enable (OE) control for 3-state outputs.  
- It is designed for high-speed digital applications with low power consumption.  

### **Features:**  
- **High-Speed Operation:** Typical propagation delay of 13ns at 5V.  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **Wide Operating Voltage:** Compatible with 2V to 6V supply range.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Balanced Propagation Delays:** Ensures reliable performance in high-speed systems.  
- **ESD Protection:** Exceeds 2000V per JESD22-A114.  

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