Description and Introduction

OCTAL D-TYPE LATCH WITH 3 STATE OUTPUTS (NON INVERTING) The M74HCT573M1R is a high-speed CMOS octal D-type transparent latch manufactured by STMicroelectronics.  

### **Manufacturer:** STMicroelectronics  

### **Specifications:**  
- **Logic Type:** Octal D-Type Transparent Latch  
- **Technology:** High-Speed CMOS (HCT)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Output Current:** ±6mA  
- **Propagation Delay:** 13ns (typical) at 5V  
- **Input Capacitance:** 3.5pF  
- **Latch-Up Performance:** >300mA  
- **Package:** SO-20  

### **Descriptions:**  
- The M74HCT573M1R features eight D-type latches with 3-state outputs.  
- It is designed for bus-oriented applications and provides high noise immunity.  
- The transparent latch allows data to pass through when the enable (LE) signal is high.  

### **Features:**  
- **3-State Outputs:** Allows direct connection to a bus.  
- **High Noise Immunity:** Compliant with HCT logic levels.  
- **Low Power Consumption:** CMOS technology ensures low static power dissipation.  
- **Wide Operating Voltage:** Supports standard 5V logic levels.  
- **Balanced Propagation Delays:** Ensures reliable high-speed operation.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official STMicroelectronics documentation.

Application Scenarios & Design Considerations

OCTAL D-TYPE LATCH WITH 3 STATE OUTPUTS (NON INVERTING)

Alternative Part Number

  • CD74HCT573M --: Same HCT octal D-type transparent latch function with 3-state outputs, direct pin-compatible replacement in SOIC package.
  • MC74HCT573ADWR2G --: HCT logic octal transparent latch with 3-state outputs, functionally equivalent and widely available alternative.
  • 74HCT573D --: Standard 74HCT573 octal D-type latch in SOIC, same logic family and pinout, suitable drop-in substitute.
