Description and Introduction

Octal Transparent D-Type Latches With 3-State Outputs The SN74HCT573DW is a high-speed octal transparent latch manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Octal Transparent Latch  
- **Technology:** HCT (High-Speed CMOS, TTL-Compatible)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Current (High/Low):** ±6mA  
- **Propagation Delay:** 13ns (typical) at 5V  
- **Input Capacitance:** 3pF (typical)  
- **Package Type:** SOIC (DW) – 20-pin  
- **Latch-Up Performance:** Exceeds 250mA per JESD 17  

### **Description:**  
The SN74HCT573DW is an octal D-type transparent latch with 3-state outputs. It is designed for bus interface applications and provides high-speed, low-power operation while maintaining compatibility with TTL logic levels.  

### **Features:**  
- **Octal Transparent Latch:** 8-bit storage with common latch enable (LE) and output enable (OE) controls.  
- **3-State Outputs:** Allows direct connection to a bus-organized system.  
- **TTL-Compatible Inputs:** Works with both CMOS and TTL logic levels.  
- **High Noise Immunity:** Typical CMOS noise margin of 0.9V at 5V.  
- **Low Power Consumption:** ICC = 4μA (max) at room temperature.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  

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