Description and Introduction

Dual 4-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs The SN74HC253NSR is a dual 4-input multiplexer with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Multiplexer  
- **Number of Circuits:** 2  
- **Number of Inputs:** 4  
- **Output Type:** 3-State  
- **Voltage Supply:** 2V to 6V  
- **Operating Temperature:** -40°C to +85°C  
- **Package/Case:** SOP-16  
- **Mounting Type:** Surface Mount  
- **Propagation Delay:** 13ns (typical at 5V)  
- **High-Level Output Current:** -5.2mA  
- **Low-Level Output Current:** 5.2mA  

### **Descriptions:**  
The SN74HC253NSR is a high-speed CMOS logic dual 4-input multiplexer with independent 3-state outputs. It selects one of four data inputs based on the select inputs (S0, S1) and routes it to the output (Y). Each multiplexer has an active-low output enable (OE) to place the output in a high-impedance state.  

### **Features:**  
- **Dual 4-to-1 Multiplexer:** Two independent multiplexers in one package.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Wide Operating Voltage:** 2V to 6V.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **High Noise Immunity:** Typical of HC logic family.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

This device is commonly used in data routing, signal switching, and bus interface applications.
