Description and Introduction

Quadruple 2-Line To 1-Line Data Selectors/Multiplexers The SN54HC157J is a high-speed CMOS logic quadruple 2-input multiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Multiplexer  
- **Number of Circuits:** 4  
- **Number of Inputs per Multiplexer:** 2  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Propagation Delay:** 13 ns (typical at 5V)  
- **Input Capacitance:** 3.5 pF (typical)  
- **Output Current:** ±5.2 mA (at 4.5V)  
- **Package Type:** CDIP (Ceramic Dual In-Line Package)  
- **Pin Count:** 16  

### **Descriptions:**  
The SN54HC157J is a high-speed CMOS device that selects one of two data inputs (A or B) based on the select input (S). It features common select and enable inputs, making it suitable for data routing, signal gating, and parallel-to-serial conversion applications.  

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **High Noise Immunity:** Typical CMOS noise margin of 30% of VCC.  
- **Balanced Propagation Delays:** Ensures consistent switching performance.  
- **Wide Operating Voltage Range:** Compatible with TTL levels at 5V supply.  
- **Schmitt Trigger Inputs:** Provides improved noise rejection on select and enable inputs.  
- **Military-Grade Reliability:** Designed for harsh environments (SN54 series).  

This device is commonly used in military, aerospace, and industrial applications due to its rugged construction and wide temperature range.
