### **Descriptions:**
- The SN74ALVCH16646DL is a 16-bit bus transceiver with D-type flip-flops, designed for 1.65V to 3.6V VCC operation.
- It supports bidirectional data flow between A and B buses, controlled by direction-control inputs (DIR).
- The output-enable (OE) input disables both ports for high-impedance state.
- Features flow-through pinout for optimized PCB layout.
### **Features:**
- **Wide Operating Voltage Range:** 1.65V to 3.6V
- **Bus-Hold on Data Inputs:** Eliminates need for external pull-up/pull-down resistors
- **Partial Power-Down Protection (Ioff):** Supports live insertion
- **3-State Outputs:** Allows multiple devices on a shared bus
- **ESD Protection:** Exceeds 2000V per JESD 22
- **Low Power Consumption:** Optimized for battery-operated applications
- **Latch-Up Performance:** Exceeds 250mA per JESD 17
This device is commonly used in data communication systems, networking equipment, and other applications requiring bidirectional data transfer.
