Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74HC640N is a high-speed CMOS logic octal bus transceiver manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Number of Bits:** 8 (Octal)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input/Output Type:** 3-State  
- **Propagation Delay:** Typically 12 ns at 5V  
- **Output Current:** ±7 mA  
- **Package Type:** PDIP (Plastic Dual-In-Line Package)  
- **Pin Count:** 20  

### **Descriptions:**  
The SN74HC640N is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features separate control inputs for direction (DIR) and output enable (OE), allowing bidirectional data flow with high-speed operation and low power consumption.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by the DIR input.  
- **3-State Outputs:** Allows connection to a bus-oriented system.  
- **High-Speed Operation:** Suitable for high-performance logic applications.  
- **Low Power Consumption:** CMOS technology ensures minimal power usage.  
- **Wide Operating Voltage:** Supports 2V to 6V, making it versatile for different logic levels.  
- **Balanced Propagation Delays:** Ensures reliable signal transmission.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.
