### **Descriptions:**
The SN74ALVTH16244DLR is a high-performance, 16-bit buffer designed for 1.65V to 3.6V VCC operation. It features TTL-compatible inputs and is optimized for low-voltage operation while maintaining high-speed performance. The device supports partial-power-down mode with bus-hold circuitry to retain data inputs when power is removed.
### **Features:**
- **Wide Operating Voltage Range:** 1.65V to 3.6V
- **Bus-Hold on Data Inputs** (Eliminates need for external pull-up/pull-down resistors)
- **Supports Mixed-Mode Signal Operation** (All inputs 5V tolerant when VCC = 0V)
- **3-State Outputs** (Allows multiple devices on a shared bus)
- **Ioff Supports Partial-Power-Down Mode**
- **ESD Protection Exceeds 2000V (HBM) and 1000V (CDM)**
- **Latch-Up Performance Exceeds 250 mA per JESD 17**
This device is commonly used in applications requiring high-speed buffering and signal driving in low-voltage systems.
