Description and Introduction

16-Bit Bus Transceiver And Register With 3-State Outputs The SN74ALVCH16646 is a 16-bit bus transceiver and register manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Technology:** ALVCH (Advanced Low-Voltage CMOS)  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Input/Output Type:** 3.3V Tolerant (5V Input Tolerant with Proper Biasing)  
- **Logic Family:** ALVC (Advanced Low-Voltage CMOS)  
- **Package Options:** 56-pin TSSOP, 56-pin TVSOP  

### **Descriptions:**  
- The SN74ALVCH16646 is a 16-bit bus transceiver with 3-state outputs and D-type registers.  
- It supports bidirectional data flow between A and B buses.  
- Features separate control inputs for data flow direction (DIR) and output enable (OE).  
- Designed for low-voltage, high-speed operation in mixed-voltage systems.  

### **Features:**  
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Partial Power-Down Protection:** Supports Ioff circuitry to disable outputs when powered off.  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **High-Speed Operation:** Optimized for 3.3V systems with fast propagation delays.  
- **ESD Protection:** Exceeds 2000V HBM (Human Body Model) and 1000V CDM (Charged Device Model).
