Description and Introduction

Octal Transparent D-Type Latches With 3-State Outputs The SN74HC573AN is a high-speed octal transparent latch with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Octal Transparent Latch  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply Range:** 2V to 6V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** 20-Pin PDIP (Plastic Dual In-Line Package)  
- **Propagation Delay:** 13 ns (typical at 5V)  
- **Output Current (High/Low):** ±7 mA  
- **Latch-Up Performance:** 250 mA  

### **Descriptions and Features:**  
- **Octal D-Type Transparent Latches:** Each latch has a D-type input and 3-state output.  
- **3-State Outputs:** Allows direct connection to a bus-organized system.  
- **Latch Enable (LE) Input:** When high, the outputs follow the data inputs; when low, the outputs are latched.  
- **Output Enable (OE) Input:** Controls the 3-state outputs (active low).  
- **Wide Operating Voltage:** Supports 2V to 6V operation.  
- **Balanced Propagation Delays:** Ensures consistent timing performance.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **High Noise Immunity:** Typical of CMOS devices.  

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