Description and Introduction

16-Bit Bus Transceiver With 3-State Outputs The SN74AVC16245 is a 16-bit bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Technology:** AVC (Advanced Very-Low-Voltage CMOS)  
- **Operating Voltage Range:** 1.2V to 3.6V  
- **Input/Output Voltage Range:** 0V to 3.6V  
- **Max Data Rate:** Up to 380 Mbps  
- **Number of Channels:** 16 (bidirectional)  
- **Logic Type:** Bus Transceiver  
- **Direction Control:** DIR pin controls data flow  
- **Output Drive Strength:** ±12 mA at 3.3V  
- **Propagation Delay:** ~2.7 ns (3.3V)  
- **I/O Type:** 3.6V Tolerant  
- **Package Options:** TSSOP (48-pin), TVSOP (48-pin)  

### **Descriptions:**  
The SN74AVC16245 is a 16-bit non-inverting bus transceiver designed for asynchronous communication between data buses. It features bidirectional data flow controlled by the DIR (Direction Control) pin. It supports mixed-voltage applications with 3.6V-tolerant I/Os, making it suitable for interfacing between different voltage domains (1.2V to 3.6V).  

### **Features:**  
- **Wide Operating Voltage:** Supports 1.2V to 3.6V for versatile applications.  
- **3.6V-Tolerant Inputs/Outputs:** Allows interfacing with higher-voltage systems.  
- **Partial Power-Down Protection:** I/Os remain high-impedance when VCC is 0V.  
- **Low Power Consumption:** Optimized for battery-powered devices.  
- **Bus-Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **ESD Protection:** Exceeds 2000V (HBM) for robustness.  
- **Flow-Through Pinout:** Simplifies PCB layout.

Application Scenarios & Design Considerations

16-Bit Bus Transceiver With 3-State Outputs

Alternative Part Number

  • 74AVC16245DGG --: Same 16-bit dual-supply voltage-level translating transceiver function with 3.6 V tolerant I/O, offered by a different vendor with a different naming prefix.
  • PI74AVC16245A --: Pin-compatible 16-bit AVC-series bus transceiver with similar 1.2-3.6 V operating range and low propagation delay.
  • 74AVCH16245 --: AVCH-series 16-bit transceiver with bus-hold inputs, functionally equivalent and usable as a drop-in alternative in most level-shifting designs.
  • 74AVC16245DGVR --: Same 16-bit dual-supply voltage-level translating transceiver function with 3.6V max VCC and similar speed, offered by a different vendor with a distinct part naming.
  • 74LVC16245ADGG --: 16-bit bus transceiver with 3.3V operation and 5V tolerant inputs; functionally similar for level-shifting bus interfaces, from a different series and manufacturer.
  • SN74LVC16245ADGGR --: TI 16-bit bus transceiver in the LVC family, pin-compatible in many designs and widely available, though it lacks the full dual-supply AVC translation feature.
