Description and Introduction

CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC The TC74HC138AFN is a high-speed CMOS 3-to-8 line decoder/demultiplexer manufactured by Toshiba.  

### **Specifications:**  
- **Logic Type:** Decoder/Demultiplexer  
- **Number of Input Lines:** 3 (A0, A1, A2)  
- **Number of Output Lines:** 8 (Y0-Y7, active low)  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOP-16 (Plastic Small Outline Package)  
- **Propagation Delay:** 13 ns (typical at 5V)  
- **Power Dissipation:** 500 mW (max)  

### **Descriptions and Features:**  
- Decodes 3 binary input signals into one of eight mutually exclusive outputs (active low).  
- Can also function as a demultiplexer with the enable input acting as a data input.  
- Low power consumption due to CMOS technology.  
- High noise immunity.  
- Compatible with TTL inputs.  
- Outputs can drive up to 10 LSTTL loads.  
- Suitable for memory address decoding and other logic applications.
