Description and Introduction

High Speed CMOS Logic Octal Inverting Bus Transceiver with 3-State Outputs The CD54HCT640F3A is a high-speed CMOS logic octal bus transceiver manufactured by Texas Instruments (TI). Here are the key specifications from Ic-phoenix technical data files:

1. **Logic Type**: Octal Bus Transceiver (3-state outputs)  
2. **Technology**: HCT (High-Speed CMOS, TTL-compatible inputs)  
3. **Supply Voltage Range**: 4.5V to 5.5V  
4. **Operating Temperature Range**: -55°C to +125°C  
5. **Input/Output Compatibility**: TTL-level inputs, CMOS-level outputs  
6. **Propagation Delay**: Typically 13ns at 5V  
7. **Output Drive Capability**: ±6mA at 5V  
8. **Package Type**: Ceramic Flatpack (F3A)  
9. **Pin Count**: 20  
10. **Direction Control**: Separate OE (Output Enable) and DIR (Direction) control pins  
11. **Features**: Non-inverting data path, 3-state outputs for bus-oriented applications  

This device is designed for bidirectional data transfer between buses and is commonly used in industrial, military, and high-reliability applications due to its extended temperature range.  

(Note: Always verify datasheet details for exact performance characteristics.)
