Description and Introduction

4-Line To 10-Line Decoders (1 of 10) The SN74HC42D is a decoder/demultiplexer IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** BCD-to-Decimal Decoder/Demultiplexer  
- **Number of Input Lines:** 4 (BCD input)  
- **Number of Output Lines:** 10 (Decimal outputs, active-low)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-16  
- **Output Type:** Active Low  
- **Propagation Delay:** Typically 13 ns at 5V  
- **Low Power Consumption:** CMOS Technology  

### **Description:**  
The SN74HC42D is a high-speed CMOS logic device that converts a 4-bit Binary-Coded Decimal (BCD) input into one of ten mutually exclusive outputs. It functions as both a decoder and a demultiplexer, with active-low outputs that ensure only one output is low at any given time based on the input code.  

### **Features:**  
- **BCD-to-Decimal Conversion:** Decodes 4-bit BCD inputs to 10-line decimal outputs.  
- **Demultiplexing Capability:** Can function as a 1-line-to-10-line demultiplexer.  
- **Wide Operating Voltage:** Supports 2V to 6V, making it compatible with various logic levels.  
- **High Noise Immunity:** CMOS technology ensures reliable performance in noisy environments.  
- **Low Power Consumption:** Ideal for battery-operated and power-sensitive applications.  
- **Standard SOIC-16 Package:** Compact and suitable for surface-mount PCB designs.  

This device is commonly used in digital systems, display drivers, and data routing applications.
