Description and Introduction

Octal Transparent D-Type Latches With 3-State Outputs The SN74F573N is an octal transparent D-type latch with 3-state outputs, manufactured by Texas Instruments.  

### **Specifications:**  
- **Logic Type:** D-Type Latch  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply Range:** 4.5V to 5.5V  
- **High-Level Output Current:** -15mA  
- **Low-Level Output Current:** 64mA  
- **Propagation Delay Time (Max):** 7.5ns at 5V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package / Case:** PDIP-20  

### **Descriptions:**  
The SN74F573N is an octal transparent latch designed for bus-organized systems. It features 3-state outputs for direct interface with bus lines. The latch is transparent when the Latch Enable (LE) input is high, allowing data to pass through. When LE goes low, the data is latched. The Output Enable (OE) input controls the 3-state outputs.  

### **Features:**  
- **Octal D-Type Latch** with 3-state outputs  
- **Bus-Structured Pinout** for easy PCB layout  
- **High-Speed Operation** (typical propagation delay of 5ns)  
- **Wide Operating Voltage Range** (4.5V to 5.5V)  
- **Low Power Consumption** (typical ICC of 50mA)  
- **ESD Protection** exceeds 2000V per JESD 22  

This device is commonly used in memory address latching, data buffering, and bus interfacing applications.
