Description and Introduction

QUAD 2 CHANNEL MULTIPLEXER (3-STATE) The M74HCT257M1R is a quad 2-input multiplexer with 3-state outputs, manufactured by STMicroelectronics (ST).  

### **Key Specifications:**  
- **Logic Family:** HCT (High-Speed CMOS, TTL-compatible inputs)  
- **Number of Channels:** 4  
- **Input Type:** TTL-compatible  
- **Output Type:** 3-state  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-16  

### **Descriptions & Features:**  
- **Function:** Selects 1 of 2 data sources per channel based on a common select input.  
- **3-State Outputs:** Allows outputs to be disabled (high impedance) for bus-oriented applications.  
- **Low Power Consumption:** CMOS technology ensures low static and dynamic power dissipation.  
- **High Noise Immunity:** Typical of HCT family devices.  
- **Applications:** Data routing, bus systems, and signal multiplexing.  

This device is designed for use in digital systems requiring TTL compatibility while benefiting from CMOS power efficiency.
