Description and Introduction

OCTAL BUS TRANSCEIVER (3-STATE INVERTING( The M74HCT640M1R is a high-speed CMOS octal bus transceiver manufactured by STMicroelectronics (ST). Here are the key specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Technology:** High-Speed CMOS (HCT)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Input/Output Compatibility:** TTL-Level  
- **Propagation Delay:** Typically 15 ns at 5V  
- **Output Drive Capability:** 6 mA at 5V  
- **Package:** SO-20  

### **Descriptions:**  
- The M74HCT640M1R is an octal bus transceiver with 3-state outputs.  
- It features non-inverting bidirectional data flow between buses.  
- Direction control (DIR) determines data flow from A to B or B to A.  
- Output enable (OE) controls the outputs in high-impedance mode.  

### **Features:**  
- **Octal Bidirectional Transceiver:** 8-bit data transfer in both directions.  
- **3-State Outputs:** Allows bus isolation when disabled.  
- **TTL-Compatible Inputs:** Works with TTL logic levels.  
- **Low Power Consumption:** CMOS technology ensures low static power dissipation.  
- **Wide Operating Voltage:** Supports standard 5V logic systems.  
- **ESD Protection:** HBM > 2000V.  

This information is strictly based on the manufacturer's datasheet.
