Description and Introduction

Octal Transparent D-Type Latches With 3-State Outputs The SN74ABT573ADBR is a high-performance octal transparent D-type latch manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Technology Family:** ABT (Advanced BiCMOS Technology)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Output Type:** 3-State  
- **Number of Bits:** 8 (Octal)  
- **Latch Type:** Transparent  
- **Package Type:** SSOP (Shrink Small Outline Package)  
- **Package Pins:** 20 (DBR suffix)  
- **Propagation Delay:** 4.5 ns (max) at 5V  
- **Output Drive Capability:** ±24 mA  

### **Descriptions:**
- The SN74ABT573ADBR is an octal transparent latch with 3-state outputs designed for bus-oriented applications.  
- It features a latch-enable (LE) input for data storage and an output-enable (OE) input for 3-state control.  
- When LE is high, the Q outputs follow the D inputs; when LE transitions low, the data is latched.  
- The outputs are disabled when OE is high, allowing multiple devices to share a common bus.  

### **Features:**
- **High-Speed Operation:** Optimized for 5V systems with fast propagation delays.  
- **Bus-Friendly 3-State Outputs:** Supports bus sharing without contention.  
- **BiCMOS Technology:** Combines high-speed performance with low power consumption.  
- **Wide Operating Voltage:** Compatible with 5V TTL systems.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

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