Description and Introduction

Octal Bus Transceiver With 3-State Outputs The SN74ALVCH245PWR is a manufacturer by Texas Instruments. Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Technology:** CMOS  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **Number of Channels:** 8  
- **Input/Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-20  
- **Mounting Type:** Surface Mount  
- **High-Level Output Current:** -24mA  
- **Low-Level Output Current:** 24mA  
- **Propagation Delay Time:** 2.3ns (max) at 3.3V  

### **Description:**  
The SN74ALVCH245PWR is an octal bus transceiver designed for 1.65V to 3.6V VCC operation. It features non-inverting 3-state outputs and is designed for asynchronous communication between data buses. The direction control (DIR) input determines data flow, while the output-enable (OE) input disables the outputs when high.  

### **Features:**  
- **Wide Operating Voltage:** 1.65V to 3.6V  
- **Supports Partial-Power-Down Mode Operation**  
- **Bus-Hold on Data Inputs Eliminates Need for External Pull-Up/Pull-Down Resistors**  
- **Latch-Up Performance Exceeds 250mA per JESD 17**  
- **ESD Protection Exceeds JESD 22 (2000V HBM, 1000V CDM)**  
- **3-State Outputs for Bus Isolation**  
- **Flow-Through Pinout for Easy PCB Layout**

Application Scenarios & Design Considerations

Octal Bus Transceiver With 3-State Outputs

Alternative Part Number

  • 74ALVCH245PW,118 --: Same ALVCH245 octal bus transceiver function in TSSOP-20 package from NXP, a direct pin-compatible alternative with equivalent 3.3V ALVC logic family performance.
  • 74ALVCH245DGVRE4 --: TI ALVCH245 in TVSOP package offering the same bus transceiver functionality and electrical characteristics, suitable when a smaller package footprint is acceptable.
  • 74ALVCH245APW --: Nexperia ALVCH245A in TSSOP-20 provides equivalent octal bus transceiver operation with 3-state outputs, a viable second-source option for the same logic function.
  • 74ALVCH245PW --: Same ALVCH245 octal bus transceiver function in TSSOP package, pin-compatible with the TI device and widely available from a different vendor.
  • 74ALVCH245DGG --: ALVCH245 transceiver in TSSOP-20 (DGG) package, same electrical function and pinout, alternate series naming for easy distinction.
