Description and Introduction

Single 2-Line to 1-Line Data Selector/Multiplexer 8-SM8 -40 to 85 The **SN74LVC2G157DCTRG4** is a dual 2-input multiplexer manufactured by **Texas Instruments (TI)**. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 1.65V to 5.5V  
- **Input Voltage Range:** 0V to VCC  
- **Output Voltage Range:** 0V to VCC  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SSOP (DCT)  
- **Logic Family:** LVC (Low-Voltage CMOS)  
- **Number of Channels:** 2  
- **Propagation Delay:** 3.7 ns (typical at 3.3V)  
- **Input Capacitance:** 3 pF (typical)  
- **Output Drive Capability:** ±24 mA at 3.3V  

### **Descriptions:**
- The SN74LVC2G157DCTRG4 is a **dual 2-input multiplexer** that selects one of two data inputs based on the select input (S).  
- It is designed for **low-voltage operation** (1.65V to 5.5V), making it suitable for battery-powered and mixed-voltage applications.  
- The device features **high-speed operation** and **low power consumption**.  
- It has **overvoltage-tolerant inputs**, allowing it to interface with higher-voltage logic levels.  

### **Features:**
- **Wide Operating Voltage Range:** 1.65V to 5.5V  
- **Low Power Consumption:** ICC = 10 µA (max)  
- **High Noise Immunity**  
- **Schmitt-Trigger Inputs** for improved noise rejection  
- **Latch-Up Performance Exceeds 250 mA per JESD 17**  
- **ESD Protection:**  
  - HBM (Human Body Model): 2000V  
  - CDM (Charged Device Model): 1000V  
- **Packaging:** Green (RoHS & no Sb/Br)  

This device is commonly used in **data routing, signal switching, and multiplexing applications** in consumer electronics, industrial systems, and communication devices.

Application Scenarios & Design Considerations

Single 2-Line to 1-Line Data Selector/Multiplexer 8-SM8 -40 to 85

Alternative Part Number

  • 74LVC2G157DP-Q100 --: Same dual 2-input multiplexer function in the LVC family with comparable 1.65-5.5V operation and small package, suitable as a direct functional replacement.
  • NC7SZ157P6X --: Single 2-input multiplexer in TinyLogic with similar LVC-compatible logic levels and tiny package, good fit when only one mux channel is needed.
  • MC74LCX157DTR2G --: Quad 2-input multiplexer in LCX logic with 2.3-3.6V operation and TSSOP package, offering extra channels for designs that can use a quad device.
