Description and Introduction

3.3-V ABT Scan Test Devices With 20-Bit Universal Bus Transceivers The SN74LVTH18514 is a 20-bit universal bus transceiver manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Technology:** LVTH (Low-Voltage BiCMOS Technology with 3.3V TTL-compatible inputs)  
- **Operating Voltage:** 2.7V to 3.6V  
- **Logic Type:** Universal Bus Transceiver  
- **Number of Bits:** 20  
- **I/O Type:** 3-State  
- **Propagation Delay:** Typically 3.8 ns (max 6.5 ns)  
- **Output Drive:** ±12 mA (balanced output drive)  
- **ESD Protection:** > 2000V (HBM)  

### **Descriptions & Features:**  
- Designed for low-voltage (3.3V) operation with 5V-tolerant inputs.  
- Supports bidirectional data flow between A and B ports.  
- Features 3-state outputs for bus-oriented applications.  
- Includes bus-hold circuitry to prevent floating inputs.  
- Compatible with TTL levels for mixed-voltage systems.  
- Available in various package options (e.g., TSSOP, TVSOP).  

For detailed electrical characteristics and pin configurations, refer to the official TI datasheet.

Application Scenarios & Design Considerations

3.3-V ABT Scan Test Devices With 20-Bit Universal Bus Transceivers

Alternative Part Number

  • 74LVTH18514MTD --: Same 18-bit universal bus transceiver function with boundary scan, direct pin-compatible second source in the LVTH family.
  • 74LVT18514MTD --: Equivalent 18-bit universal bus transceiver with IEEE 1149.1 boundary scan, LVT logic family offers similar drive and speed.
  • CY74FCT18514TPVC --: FCT-family 18-bit universal bus transceiver with boundary scan, functionally comparable alternative when LVTH parts are unavailable.
