Description and Introduction

Octal Transparent D-Type Latches With 3-State Outputs The SN74AHC573DW is a high-speed CMOS octal transparent latch manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Technology:** CMOS  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **High-Speed Operation:** tpd = 8.5 ns (max) at 5 V  
- **Low Power Consumption:** ICC = 8 µA (max)  
- **Output Drive Capability:** ±24 mA at 4.5 V  
- **Latch-Up Performance:** Exceeds 250 mA per JESD 17  
- **ESD Protection:**  
  - HBM: 2000 V  
  - CDM: 1000 V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** SOIC (DW) – 20-pin  

### **Description:**  
The SN74AHC573DW is an octal transparent latch with 3-state outputs. It is designed for bus interface applications and features a latch enable (LE) input and an output enable (OE) input. When LE is high, the data passes through to the outputs. When LE transitions low, the data is latched. The outputs can be placed in a high-impedance state using the OE input.

### **Features:**  
- **Octal D-Type Transparent Latch**  
- **3-State Outputs**  
- **Buffered Inputs**  
- **Balanced Propagation Delays**  
- **Wide Operating Voltage Range (2 V to 5.5 V)**  
- **Low Power Consumption**  
- **High Noise Immunity**  
- **Bus-Structured Pinout**  

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