- **Low-Level Output Current:** 64 mA
- **Mounting Type:** Surface Mount

### **Descriptions:**
- The SN74ABT646ADW combines an octal D-type flip-flop with a transceiver to allow bidirectional data flow between buses.
- It features 3-state outputs for bus-oriented applications.
- The device operates from 4.5 V to 5.5 V and is designed for high-speed, low-power applications.

### **Features:**
- **Bidirectional Bus Interface**
- **3-State Outputs**
- **Flow-Through Pinout for Easy PCB Layout**
- **High-Speed Operation (4.5 ns max propagation delay)**
- **Supports Mixed-Mode Signal Operation (5-V Input and Output Voltages with 3.3-V VCC)**
- **ESD Protection Exceeds 2000 V Per MIL-STD-883, Method 3015**
- **Latch-Up Performance Exceeds 500 mA Per JESD 17**

This device is commonly used in data communication systems, networking equipment, and other applications requiring bidirectional data transfer.
