- **Low-Level Output Current:** 5.2 mA  

### **Description:**  
The SN74HC251DBR is an 8-to-1 multiplexer with 3-state outputs. It selects one of eight data inputs (D0–D7) based on the select lines (A, B, C) and routes it to the output (Y). The output can be disabled using the output enable (OE) pin, placing it in a high-impedance state.  

### **Features:**  
- **Wide Operating Voltage:** 2V to 6V  
- **Low Power Consumption:** 80 µA (max)  
- **High Noise Immunity:** CMOS Technology  
- **3-State Output:** Allows bus-oriented applications  
- **Balanced Propagation Delays**  
- **Schmitt-Trigger Inputs for Noise Reduction**  

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