Description and Introduction

3.3-V ABT 16-Bit Registered Transceivers With 3-State Outputs The SN74LVT16952DLR is a 16-bit bus transceiver and register manufactured by Texas Instruments (TI/BB).  

### **Specifications:**  
- **Logic Type:** Bus Transceiver, Non-Inverting  
- **Number of Bits:** 16  
- **Voltage Supply:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Type:** 3-State  
- **Package:** SSOP (DLR) - 56-pin  
- **Input/Output Compatibility:** TTL, 5V Tolerant Inputs  
- **Propagation Delay:** Typically 3.5 ns  
- **High-Level Output Current:** -32 mA  
- **Low-Level Output Current:** 64 mA  

### **Descriptions:**  
- Designed for low-voltage (3.3V) applications.  
- Combines D-type latches and transceivers for bidirectional data flow.  
- Features separate control inputs for data direction and output enable.  

### **Features:**  
- **3.3V Operation** with 5V Tolerant Inputs  
- **Bus Hold on Data Inputs** (Eliminates Need for External Pull-Up/Pull-Down Resistors)  
- **Supports Mixed-Mode Signal Operation** (5V Input/Output with 3.3V Supply)  
- **Flow-Through Pinout** (Optimized for PCB Layout)  
- **ESD Protection** (Exceeds 2000V per JESD 22)  

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

Application Scenarios & Design Considerations

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

Alternative Part Number

  • 74LVT16952DGG --: Same 16-bit registered transceiver function in the LVT family, available from NXP with equivalent 3.3V operation and similar speed; check package and pinout compatibility.
  • 74LVT16501ADGG --: Similar LVT 18-bit universal bus transceiver offering comparable voltage translation and drive; verify bit width and control pin differences before substitution.
  • 74ALVT16952DGG --: ALVT series 16-bit registered transceiver with similar function and improved drive; confirm timing and package compatibility for the target design.
  • 74LVT16952PV --: Pin-compatible LVT 16-bit registered transceiver with similar speed and drive characteristics, offered in SSOP package.
  • 74ABT16952DGG --: ABT-family 16-bit registered transceiver with comparable bus-hold and drive capability, usable as a functional substitute where LVT speed is not critical.
