Description and Introduction

Octal Bus Transceivers With 3-State Outputs 20-TSSOP -40 to 125 The SN74AHCT245PWRG4 is a bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology Family:** AHCT  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Number of Channels:** 8  
- **Logic Type:** Octal Bus Transceiver  
- **Output Type:** 3-State  
- **Package / Case:** TSSOP-20  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 7.5 ns (typical)  
- **High-Level Output Current:** -8 mA  
- **Low-Level Output Current:** 8 mA  

### **Descriptions:**  
The SN74AHCT245PWRG4 is an octal bus transceiver designed for asynchronous communication between data buses. It features non-inverting 3-state outputs and is compatible with TTL levels. The direction of data flow is controlled by the DIR (Direction Control) input, while the Output Enable (OE) input disables the outputs for bus isolation.  

### **Features:**  
- **Wide Operating Voltage Range:** 4.5V to 5.5V  
- **TTL-Compatible Inputs**  
- **3-State Outputs for Bus Isolation**  
- **Bidirectional Data Flow Control (DIR Pin)**  
- **Low Power Consumption (ICC = 4 µA Max)**  
- **ESD Protection Exceeds 2000V (HBM)**  
- **Latch-Up Performance Exceeds 250 mA per JESD 17**  

This device is commonly used in applications requiring bidirectional data transfer, such as microprocessor/microcontroller interfacing and data bus buffering.

Application Scenarios & Design Considerations

Octal Bus Transceivers With 3-State Outputs 20-TSSOP -40 to 125

Alternative Part Number

  • 74AHCT245PW,118 --: Same octal bus transceiver function with 3-state outputs in TSSOP package, direct functional equivalent from a different vendor.
  • MC74AHCT245ADTR2G --: AHCT-family octal bus transceiver with 3-state outputs, TSSOP package, compatible logic levels and pinout.
  • SN74AHCT245DW --: Same TI AHCT245 die in SOIC-20 wide-body package; suitable when board space allows a wider package footprint.
