Description and Introduction

OCTAL D-TYPE LATCH WITH 3-STATE OUTPUT (NON INVERTING) The M74HC573M1R is a high-speed CMOS octal D-type latch with 3-state outputs, manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Technology:** High-Speed CMOS  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** Compliant with standard CMOS levels  
- **Low Power Consumption:** Optimized for battery-operated devices  
- **Operating Temperature Range:** -40°C to +125°C  
- **Output Current:** ±6mA at 4.5V supply  
- **Latch-Up Performance:** Exceeds 250mA per JESD 78 standard  
- **Package:** SO-20 (Small Outline)  

### **Descriptions:**  
- The M74HC573M1R consists of eight D-type transparent latches with 3-state outputs.  
- It is designed for bus-oriented applications where data needs to be retained or driven onto a shared bus.  
- The latch enable (LE) input controls data storage, while the output enable (OE) input enables/disables the outputs.  

### **Features:**  
- **Octal D-Type Latch with 3-State Outputs**  
- **Non-Inverting Outputs**  
- **Common 3-State Output Enable (OE) Input**  
- **Common Latch Enable (LE) Input**  
- **Balanced Propagation Delays**  
- **Wide Operating Voltage Range (2V to 6V)**  
- **Compatible with TTL Input Levels**  
- **ESD Protection (HBM > 2000V, MM > 200V)**  

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