Description and Introduction

Octal D-Type Transparent Latches With 3-State Outputs The SN74AC573N is an octal transparent D-type latch manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Logic Type:** Octal Transparent D-Type Latch  
- **Technology:** Advanced CMOS (AC)  
- **Number of Bits:** 8  
- **Supply Voltage Range:** 2 V to 6 V  
- **High-Level Output Current:** -24 mA  
- **Low-Level Output Current:** 24 mA  
- **Propagation Delay Time:** 7.5 ns (typical) at 5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** PDIP-20 (Plastic Dual In-Line Package)  

### **Descriptions:**
- The SN74AC573N is a high-speed, low-power octal latch with 3-state outputs.  
- It features transparent latch operation, meaning the outputs follow the data inputs when the latch enable (LE) is high.  
- When LE goes low, the data is latched and held until LE is high again.  
- The output enable (OE) input controls the 3-state outputs, allowing multiple devices to share a common bus.  

### **Features:**
- **3-State Outputs:** Allows bus-oriented applications.  
- **High-Speed Operation:** Optimized for 5-V systems.  
- **Balanced Propagation Delays:** Ensures reliable performance.  
- **Low Power Consumption:** Typical ICC of 8 µA.  
- **Wide Operating Voltage:** 2 V to 6 V.  
- **ESD Protection:** Exceeds 2000 V per JESD 22.  

This device is commonly used in data storage, buffering, and bus interface applications.
