16-BIT DUAL SUPPLY VOLTAGE INTERFACE BUS TRANSCEIVER WITH SERIES RESISTOR The **TC74LCXR163245FT** is a **16-bit bus transceiver** manufactured by **Toshiba**.  

### **Key Specifications:**  
- **Logic Family:** Low-Voltage CMOS (LCX)  
- **Voltage Range:** **1.65V to 3.6V** (supports mixed-voltage operation)  
- **Bus Hold:** Yes (eliminates the need for external pull-up/pull-down resistors)  
- **Direction Control:** **DIR pin** for controlling data flow (A to B or B to A)  
- **Output Drive:** ±24mA (balanced drive capability)  
- **Package Type:** **TSSOP-48** (thin shrink small outline package)  
- **Operating Temperature:** **-40°C to +85°C**  

### **Features:**  
- **Bi-directional voltage translation** (supports mixed 1.8V, 2.5V, and 3.3V systems)  
- **3-state outputs** (high-impedance when disabled)  
- **Power-down protection** (inputs/outputs tolerate voltages up to 3.6V)  
- **Low power consumption** (optimized for battery-operated devices)  
- **ESD Protection:** Exceeds **2000V HBM** (Human Body Model)  

### **Applications:**  
- **Data communication systems**  
- **Microprocessor/microcontroller interfaces**  
- **Mixed-voltage level translation**  
- **Portable and battery-powered devices**  

This device is designed for **high-speed, low-power** applications requiring **bidirectional level shifting**.
