Description and Introduction

18-Bit Universal Bus Transceiver With 3-State Outputs The SN74ALVCH16501DGGR is a 18-bit universal bus transceiver manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** Universal Bus Transceiver  
- **Number of Bits:** 18  
- **Voltage Supply:** 1.65V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Package / Case:** TSSOP-56  
- **Mounting Type:** Surface Mount  
- **High-Level Output Current:** -12mA  
- **Low-Level Output Current:** 12mA  
- **Propagation Delay Time:** 2.9ns (max) at 3.3V  
- **Moisture Sensitivity Level (MSL):** 1 (Unlimited)  

### **Descriptions and Features:**  
- **Universal Bus Transceiver:** Combines D-type latches and D-type flip-flops for flexible data flow control.  
- **Wide Operating Voltage:** Supports 1.65V to 3.6V, making it suitable for mixed-voltage systems.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **Bus-Hold Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Partial Power-Down Protection:** Supports Ioff to prevent current backflow when powered down.  
- **ESD Protection:** Exceeds 2000V (HBM) and 1000V (CDM) for improved reliability.  
- **Flow-Through Pinout:** Optimized for PCB layout efficiency.  

This device is commonly used in data communication, networking, and computing systems requiring bidirectional data transfer.

Application Scenarios & Design Considerations

18-Bit Universal Bus Transceiver With 3-State Outputs

Alternative Part Number

  • 74ALVCH16501DGG --: Same 18-bit universal bus transceiver function with ALVCH family logic and TSSOP-56 package, offered by Nexperia as a direct functional equivalent.
  • 74ALVCH16501PA --: Equivalent 18-bit universal bus transceiver in the ALVCH logic family with similar voltage range and drive characteristics, suitable as a drop-in functional replacement.
  • 74ALVCH16501DGV --: Same ALVCH 18-bit bus transceiver function in a TVSOP package; electrically compatible alternative when package footprint can be adapted.
  • 74ALVCH16501DGVRE4 --: Equivalent ALVCH 18-bit bus transceiver from the same vendor in a TVSOP package, suitable when board layout allows a smaller footprint.
  • PI74ALVCH16501A --: Drop-in ALVCH 18-bit universal bus transceiver with matching voltage range and TSSOP-56 option, offering a second-source supply alternative.
