Description and Introduction

3.3-V ABT 16-Bit Registered Transceivers With 3-State Outputs The SN74LVT16952DL is a 16-bit bus transceiver and register manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Bus Transceiver, Non-Inverting  
- **Number of Bits:** 16  
- **Voltage Supply:** 2.7V to 3.6V  
- **Operating Temperature:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Package:** SSOP (DL) - 56-pin  
- **Propagation Delay:** 3.5ns (max) at 3.3V  
- **Input/Output Compatibility:** 5V Tolerant Inputs  

### **Descriptions:**  
The SN74LVT16952DL combines D-type latches and D-type flip-flops to allow data flow in transparent, latched, or clocked modes. It supports bidirectional data transfer between buses and features 3-state outputs for bus-oriented applications.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by output-enable (OEAB, OEBA) and direction-control (DIR) inputs.  
- **Registered or Transparent Mode:** Selectable via latch-enable (LEAB, LEBA) inputs.  
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **High-Drive Outputs:** -32mA IOH, 64mA IOL.  
- **5V-Tolerant Inputs:** Allows interfacing with 5V logic levels.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

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

Application Scenarios & Design Considerations

3.3-V ABT 16-Bit Registered Transceivers With 3-State Outputs

Alternative Part Number

  • 74LVT16952DG --: Same 16-bit registered transceiver function in the LVT family with comparable 3.3V operation and SSOP-style packaging.
  • 74LVT16501ADGG --: LVT 18-bit universal bus transceiver offering similar voltage translation and bus-interface capability for the same application.
  • 74ABT16952DGG --: ABT-family 16-bit registered transceiver with similar function and speed, usable where LVT is unavailable with minor timing review.
  • CY74FCT16952T --: FCT 16-bit registered transceiver with similar bus-hold and drive characteristics, usable as a functional substitute where LVT is not critical.
