Description and Introduction

16-Bit Bus Transceiver And Register With 3-State Outputs The SN74LVCH16646A is a 16-bit bus transceiver and register manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Technology Family:** LVCH (Low-Voltage CMOS with 3.3V tolerance)  
- **Supply Voltage Range:** 1.65V to 3.6V  
- **Input Voltage Range:** 0V to 5.5V (tolerant)  
- **Output Drive:** ±24mA at 3.3V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Options:** 56-pin TSSOP, 56-pin TVSOP  
- **Logic Type:** Bus Transceiver/Register  
- **Number of Channels:** 16  
- **Propagation Delay:** 3.8ns (max) at 3.3V  

### **Descriptions:**  
- The SN74LVCH16646A is a 16-bit bus transceiver with 3-state outputs and D-type registers.  
- It supports bidirectional data flow between A and B buses.  
- Designed for low-voltage (1.65V to 3.6V) applications with 5V-tolerant inputs.  
- Features output edge-rate control to reduce noise in high-speed applications.  

### **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.  
- **Flow-Through Pinout:** Optimized for PCB layout efficiency.  
- **ESD Protection:** Exceeds 2000V (HBM) and 1000V (CDM).  
- **Balanced Output Drive:** Minimizes ground bounce and switching noise.
