Description and Introduction

Octal Bus Transceivers With 3-State Outputs 20-SSOP -40 to 85 The SN74HCT245DBRG4 is a part manufactured by BB/TI (Texas Instruments). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Technology Family:** HCT  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Number of Channels:** 8  
- **Logic Type:** Octal Bus Transceiver  
- **Input Type:** Schmitt Trigger  
- **Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package/Case:** SSOP-20  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 13 ns (typical)  
- **High-Level Output Current:** -6 mA  
- **Low-Level Output Current:** 6 mA  

### **Descriptions:**  
The SN74HCT245DBRG4 is an octal bus transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and is compatible with TTL inputs. The direction of data flow is controlled by the DIR (Direction Control) input, and the outputs can be disabled using the OE (Output Enable) input.  

### **Features:**  
- **Wide Operating Voltage Range:** 4.5V to 5.5V  
- **Balanced Propagation Delays**  
- **3-State Outputs for Bus-Oriented Applications**  
- **Schmitt-Trigger Inputs for Noise Immunity**  
- **TTL-Compatible Input Levels**  
- **ESD Protection Exceeds JESD 22**  

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

Application Scenarios & Design Considerations

Octal Bus Transceivers With 3-State Outputs 20-SSOP -40 to 85

Alternative Part Number

  • MC74HCT245ADWR2G --: Direct logic-equivalent octal bus transceiver in the same HCT family with 3-state outputs, available in SOIC-20 wide-body package; pin-compatible function and widely stocked alternative to the TI device.
  • 74HCT245D,653 --: Octal bus transceiver with 3-state outputs in SOIC-20, functionally and pin-compatible with the SN74HCT245, from a major logic supplier with good availability.
  • CD74HCT245M --: Same manufacturer's CD74HCT series octal bus transceiver in SOIC-20; electrically equivalent HCT logic with 3-state outputs, useful when TI sourcing consistency is preferred.
  • 74HCT245PW,118 --: Same octal bus transceiver function with 3-state outputs in a TSSOP package, widely available and pin-compatible in function.
  • MC74HCT245ADTR2G --: HCT-family octal bus transceiver with equivalent logic thresholds and drive, suitable drop-in functional replacement.
  • CD74HCT245M96 --: Same manufacturer HCT octal bus transceiver in SOIC, electrically equivalent and easy to qualify as a substitute.
