Description and Introduction

Octal Bus Transceiver With 3-State Outputs 20-TSSOP -40 to 125 The SN74LVC245APWRG4 is a 3.3-V CMOS octal bus transceiver manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Technology Family:** LVC  
- **Supply Voltage (VCC):** 1.65 V to 3.6 V  
- **Number of Channels:** 8  
- **Input Type:** Standard  
- **Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-20  
- **Mounting Type:** Surface Mount  
- **Logic Type:** Transceiver, Non-Inverting  
- **High-Level Output Current:** -24 mA  
- **Low-Level Output Current:** 24 mA  
- **Propagation Delay Time:** 4.3 ns at 3.3 V  
- **Moisture Sensitivity Level (MSL):** 1 (Unlimited)  

### **Descriptions:**
- The SN74LVC245APWRG4 is an octal bus transceiver designed for asynchronous communication between data buses.  
- It features 3-state outputs for bus-oriented applications.  
- The direction of data flow is controlled by the direction (DIR) input.  
- The output-enable (OE) input disables the outputs for isolation.  
- Supports mixed-mode voltage operation (1.65 V to 3.6 V).  

### **Features:**
- **Wide Operating Voltage Range:** 1.65 V to 3.6 V  
- **3.6-V Tolerant Inputs and Outputs**  
- **Supports Partial Power-Down Mode Operation**  
- **±24-mA Output Drive at 3.3 V**  
- **Low Power Consumption:** ICC = 10 µA (Max)  
- **Bus-Hold on Data Inputs Eliminates Need for External Pull-Up/Pull-Down Resistors**  
- **ESD Protection Exceeds JESD 22 (2000-V Human-Body Model, 200-V Machine Model)**

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 74LVC245APW,118 --: Same octal bus transceiver function with 3.3V LVC logic family in TSSOP package, pin-compatible and widely available.
  • MC74LCX245DTG --: LCX family octal transceiver offering similar 3.3V operation and 5V-tolerant inputs, drop-in functional replacement in TSSOP.
  • SN74LVC245ADWR --: Same TI LVC245 transceiver die in a wider SOIC package, suitable when board space allows and TSSOP is unavailable.
  • 74LVC245APW-Q100,118 --: Automotive-qualified version of the same LVC245 function in TSSOP-20, offering equivalent electrical behavior with higher reliability grading; distinct series naming avoids confusion with the original TI part.
