Description and Introduction

Octal bus transceivers The SN74F245DWR is a member of the 74F logic family and is manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Number of Bits:** 8  
- **Voltage Supply Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Propagation Delay Time:** 4.5 ns (max)  
- **High-Level Output Current:** -15 mA  
- **Low-Level Output Current:** 24 mA  
- **Package / Case:** SOIC-20 (DWR)  

### **Descriptions:**  
The SN74F245DWR is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features non-inverting 3-state outputs and is controlled by a direction (DIR) pin and an output enable (OE) pin.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by the DIR pin.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **High-Speed Operation:** Optimized for fast data transfer.  
- **Wide Operating Voltage:** Supports standard 5V logic levels.  
- **ESD Protection:** Helps prevent damage from electrostatic discharge.  

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

Application Scenarios & Design Considerations

Octal bus transceivers

Alternative Part Number

  • 74F245D --: Same 74F245 octal bus transceiver function in SOIC package; NXP naming differs from the TI SN74F245DWR and is a direct functional equivalent.
  • MC74F245DW --: ON Semiconductor 74F245 octal bus transceiver in wide SOIC, functionally equivalent with different series prefix.
  • 74F245SC --: Fairchild 74F245 in SOIC package, same logic function and pinout, distinguishable naming from the original TI part.
