### **Descriptions:**
The SN74BCT573DW is an octal transparent latch with 3-state outputs designed for bus-oriented applications. It features a latch-enable (LE) input and an output-enable (OE) input for controlling data flow. When LE is high, the data passes through the latch to the outputs. When OE is low, the outputs are active; when high, the outputs are in a high-impedance state.
### **Features:**
- **Octal D-Type Transparent Latch** with 3-state outputs
- **Bus-Compatible Inputs and Outputs**
- **BiCMOS Technology** for improved speed and power efficiency
- **High-Impedance State** when OE is high
- **Latch-Up Performance** exceeds 500mA per JESD 17
- **ESD Protection** exceeds 2000V per MIL-STD-883, Method 3015
- **Wide Operating Voltage Range** (4.5V to 5.5V)
- **20-Pin SOIC Package** (DW)
