Description and Introduction

18-BIT LVTTL-TO-GTL/GTL BUS TRANSCEIVER The SN74GTL16923DGGR is a 20-bit universal bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Universal Bus Transceiver  
- **Number of Bits:** 20  
- **Voltage Supply:** 3V to 3.6V (GTL+ compatible)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 56-TSSOP  
- **Output Type:** 3-State  
- **Data Rate:** Up to 200MHz  
- **Input/Output Compatibility:** 3.3V TTL, GTL+, and LVTTL  

### **Descriptions:**  
The SN74GTL16923DGGR is designed for high-speed bus interfacing between 3.3V TTL and GTL+ environments. It supports bidirectional data flow with 3-state outputs and includes features for hot insertion and power-up protection.  

### **Features:**  
- **Bidirectional Voltage Translation:** Converts between 3.3V TTL and GTL+ signal levels.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **Hot Insertion Protection:** Prevents damage during live insertion/removal.  
- **Flow-Through Pinout:** Optimized for PCB layout efficiency.  
- **Low Power Consumption:** Designed for energy-efficient operation.  
- **ESD Protection:** Exceeds 2000V HBM (Human Body Model).  

This device is commonly used in networking, telecommunications, and computing applications requiring high-speed data transfer.

Application Scenarios & Design Considerations

18-BIT LVTTL-TO-GTL/GTL BUS TRANSCEIVER

Alternative Part Number

  • 74GTL16923DGGRE4 --: Same GTL16923 function and DGG package from TI, with E4 lead-free finish; functionally identical drop-in replacement.
  • GTLP16923DGGR --: TI GTLP-series 18-bit GTL transceiver in the same TSSOP package; similar bus-interface function with improved drive.
  • SN74GTLP16923DGGR --: TI GTLP variant of the 16923 in the same DGG package, offering equivalent GTL bus translation functionality.
  • 74GTL16923DGGRG4 --: Identical GTL16923 translator die and TSSOP-56 pinout from TI, using the Green/RoHS orderable code; electrically and functionally interchangeable with the original.
  • SN74GTL16923DGVRE4 --: Same SN74GTL16923 GTL translator family from TI in the TVSOP (DGV) package; suitable when board layout can accommodate the alternate package, offering the same logic function and voltage translation.
