Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74ABT640NSR is a bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Octal Bus Transceiver  
- **Technology:** ABT (Advanced BiCMOS Technology)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC (NSR), 20-pin  
- **Logic Family:** ABT  
- **Data Rate:** Up to 100MHz  
- **Output Type:** 3-State  
- **Input/Output Compatibility:** TTL-Level  

### **Descriptions:**  
The SN74ABT640NSR is an octal bus transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and bidirectional data flow controlled by direction (DIR) and output enable (OE) inputs. It is optimized for high-speed, low-power operation in 5V systems.

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR input.  
- **3-State Outputs:** Allows connection to a shared bus.  
- **High-Speed Operation:** Supports fast data transmission.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with TTL logic levels.  
- **Low Power Consumption:** ABT technology reduces power usage.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  
- **Flow-Through Pinout:** Simplifies PCB layout.

Application Scenarios & Design Considerations

Octal Bus Transceivers With 3-State Outputs

Alternative Part Number

  • 74ABT640D --: Same ABT640 octal transceiver function with similar speed and drive, available in SOIC package from a different vendor.
  • 74ABT245D --: Octal bus transceiver in the same ABT family with comparable drive and speed; pinout differs slightly but is a common functional substitute for bus-interface designs.
  • 74ACT640D --: Octal transceiver with TTL-compatible inputs and similar drive capability; ACT family offers a close functional match when ABT is unavailable.
