Description and Introduction

3.3-V ABT Octal Transparent D-Type Latches With 3-State Outputs The SN74LVTH573PW is a 3.3-V octal transparent D-type latch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology Family:** LVTH (Low-Voltage BiCMOS Technology with 5-V Tolerant Inputs/Outputs)  
- **Supply Voltage Range:** 2.7 V to 3.6 V  
- **High-Speed Operation:** 3.3 ns max (tpd) at 3.3 V  
- **Output Drive:** ±12 mA (at 3.0 V)  
- **Input Voltage Tolerance:** 5 V (allows interfacing with 5-V logic)  
- **Latch-Up Performance:** Exceeds 500 mA per JESD 78  
- **ESD Protection:**  
  - 2000 V Human-Body Model (A114-A)  
  - 200 V Machine Model (A115-A)  
  - 1000 V Charged-Device Model (C101)  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package Type:** TSSOP (PW) – 20-pin  

### **Description:**  
The SN74LVTH573PW is an octal transparent latch with 3-state outputs. It is designed for low-voltage (3.3-V) applications while maintaining compatibility with 5-V systems. The device features a latch-enable (LE) input and an output-enable (OE) input for controlling data flow.  

### **Features:**  
- **Octal D-Type Transparent Latch** with 3-state outputs  
- **Bus-Hold Data Inputs** eliminate the need for external pull-up/pull-down resistors  
- **5-V Tolerant Inputs/Outputs** for mixed-voltage system interfacing  
- **Supports Partial-Power-Down Mode Operation**  
- **Ioff Feature** allows live insertion without back-drive current  

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