Description and Introduction

Quadruple Low-Power Differential Line Receiver The SN75LBC173N is a quad differential line receiver manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Common-Mode Voltage Range:** ±12V  
- **Differential Input Threshold Voltage:** ±200mV  
- **Propagation Delay (Max):** 20ns  
- **Output Type:** 3-State TTL  
- **Number of Receivers:** 4  
- **Package Type:** PDIP (Plastic Dual In-Line Package)  
- **Pin Count:** 16  

### **Descriptions:**
The SN75LBC173N is designed for balanced multipoint bus transmission at data rates up to 10Mbps. It features high input impedance, allowing up to 32 transceivers on the bus. The device includes fail-safe circuitry, ensuring a high output state when inputs are open or shorted.  

### **Features:**
- **Quad Differential Line Receiver**  
- **3-State Outputs**  
- **Designed for RS-485 and RS-422 Applications**  
- **Fail-Safe Design (Ensures High Output for Open/Shorted Inputs)**  
- **High Input Impedance (Up to 32 Unit Loads on Bus)**  
- **Low Power Consumption**  
- **ESD Protection (Up to 12kV on Bus Pins)**  
- **Wide Common-Mode Voltage Range (±12V)**  

This device is commonly used in industrial control, telecommunications, and networking applications.
