Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74HC245PW is an octal bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Category:** Integrated Circuits (ICs)  
- **Family:** 74HC  
- **Type:** Bus Transceiver  
- **Number of Bits:** 8 (Octal)  
- **Voltage Supply:** 2V to 6V  
- **Logic Level:** CMOS  
- **High-Level Output Current:** -7.8mA  
- **Low-Level Output Current:** 7.8mA  
- **Propagation Delay:** 13ns (typical at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-20  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The SN74HC245PW 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) input and an output enable (OE) input. When OE is high, the outputs are in a high-impedance state.  

### **Features:**  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **Wide Operating Voltage:** 2V to 6V.  
- **High-Current Outputs:** Supports up to ±7.8mA.  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **Bidirectional Data Flow:** Controlled by the DIR pin.  
- **ESD Protection:** Exceeds JESD 22 standards (2000V HBM, 1000V CDM).  
- **Packaging:** Available in TSSOP-20 for space-constrained applications.  

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

Application Scenarios & Design Considerations

Octal Bus Transceivers With 3-State Outputs

Alternative Part Number

  • MC74HC245ADWR2G --: Octal bus transceiver in the same HC logic family with equivalent 3-state bidirectional function, widely available and pin-compatible in SOIC-wide package.
  • 74HC245D,653 --: Direct functional equivalent octal bus transceiver with 3-state outputs, same HC speed grade and SOIC package, from a major logic supplier.
  • CD74HC245M --: Same-function octal bus transceiver from the same manufacturer's CD74HC series, offering an alternative series naming while maintaining electrical compatibility.
  • CD74HC245E --: Same HC245 function from the original manufacturer in a different series prefix, ensuring logic compatibility and easy sourcing.
  • 74HC245D --: Standard 74HC245 octal transceiver with matching function and TSSOP package, a common multi-source alternative.
