Description and Introduction

3.3V CMOS 16-BIT BUS TRANSCEIVER/REGISTER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O The **IDT74LVC16646APV** is a 16-bit bus transceiver and register manufactured by **Integrated Device Technology (IDT)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Logic Family:** LVC (Low-Voltage CMOS)  
- **Number of Bits:** 16-bit  
- **Function:** Bus transceiver with 3-state outputs  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **Input/Output Compatibility:** 5V tolerant inputs  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP (Thin Shrink Small Outline Package)  
- **Pin Count:** 48  

### **Descriptions:**
- The **IDT74LVC16646APV** is designed for bidirectional data transfer between buses.  
- It features **non-inverting** outputs and **3-state buffers** for bus isolation.  
- Includes **direction control (DIR)** and **output enable (OE)** inputs for flexible data flow management.  
- Supports **partial power-down** mode for reduced power consumption.  

### **Features:**
- **Wide Voltage Range:** Operates from **1.65V to 3.6V**  
- **5V Tolerant Inputs:** Allows interfacing with 5V logic levels  
- **High-Speed Operation:** Optimized for low propagation delay  
- **3-State Outputs:** Enables bus isolation when disabled  
- **Bidirectional Data Flow:** Controlled by DIR pin  
- **Low Power Consumption:** Suitable for battery-operated devices  
- **ESD Protection:** Exceeds **2000V** (HBM)  

This device is commonly used in **data communication systems, networking equipment, and embedded applications** requiring bidirectional bus interfacing.

Application Scenarios & Design Considerations

3.3V CMOS 16-BIT BUS TRANSCEIVER/REGISTER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O

Alternative Part Number

  • SN74LVC16646APV --: Same 16-bit registered transceiver function in the LVC family with matching 56-pin SSOP package and 3.3V operation; TI is the original source of many IDT LVC logic designs.
  • 74LVC16646APVG --: Renesas acquired IDT's logic portfolio, so this is the direct functional equivalent of the IDT LVC16646A in the same PV SSOP package.
  • 74LVC16646ADGG --: Equivalent 16-bit bus transceiver/register in the LVC family with similar voltage and speed ratings; TSSOP package may require footprint check.
