Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74ACT245NSR is a manufacturer by Texas Instruments. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** Integrated Circuits (ICs)  
- **Family:** Logic - Buffers, Drivers, Receivers, Transceivers  
- **Series:** 74ACT  
- **Type:** Transceiver, Non-Inverting  
- **Number of Bits:** 8  
- **Voltage - Supply:** 4.5V to 5.5V  
- **Operating Temperature:** -40°C to 85°C  
- **Package / Case:** 20-SOIC (0.209", 5.30mm Width)  
- **Mounting Type:** Surface Mount  
- **Output Type:** 3-State  
- **Logic Level - Low:** 0.8V  
- **Logic Level - High:** 2V

- **Current - Output High, Low:** 24mA, 24mA  

### **Descriptions:**  
The SN74ACT245NSR is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features 3-state outputs for bus-oriented applications and bidirectional data flow controlled by the direction (DIR) input. The output enable (OE) input disables both outputs for isolation.  

### **Features:**  
- **Octal Bidirectional Transceiver**  
- **3-State Outputs**  
- **Non-Inverting Data Path**  
- **Wide Operating Voltage Range (4.5V to 5.5V)**  
- **Balanced Propagation Delays**  
- **High-Current Outputs (24mA)**  
- **ESD Protection Exceeds 2000V (Per JESD 22-A114)**  
- **Latch-Up Performance Exceeds 250mA (Per JESD 78)**  
- **Available in SOIC Package**  

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

Application Scenarios & Design Considerations

Octal Bus Transceivers With 3-State Outputs

Alternative Part Number

  • MC74ACT245ADWR2G --: Same ACT-family octal bus transceiver with 3-state outputs in a wide-body SOIC package, directly pin-compatible and functionally equivalent.
  • 74ACT245SCX --: Equivalent ACT-series octal bus transceiver in SOIC-20, same logic function and drive characteristics as the original.
  • CD74ACT245M96 --: Same manufacturer ACT-family octal bus transceiver in SOIC-20, identical function and compatible electrical specifications.
  • MC74ACT245DWR2G --: ACT-family octal bus transceiver in SOIC-20 wide body, matches logic family and function with different series prefix for easy distinction.
  • 74ACT245MTCX --: Equivalent 74ACT245 transceiver in TSSOP package, suitable alternative when board layout allows the smaller package.
