Description and Introduction

CMOS Digital Integrated Circuit Silicon Monolithic Octal D-Type Latch with 3-State Output The TC74AC573FT is a high-speed CMOS octal D-type latch manufactured by Toshiba. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Octal D-type transparent latch  
- **Supply Voltage Range:** 2.0V to 5.5V  
- **High-Speed Operation:**  
  - Propagation Delay Time (max): 7.5 ns (at 5V)  
- **Low Power Consumption:**  
  - Quiescent Supply Current (max): 4 µA (at 5.5V)  
- **Output Drive Capability:**  
  - 24 mA (sink/source at 5V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-20  

### **Descriptions:**  
- The TC74AC573FT is an 8-bit transparent latch with 3-state outputs.  
- It features a latch enable (LE) input and an output enable (OE) input for controlling data flow.  
- When **LE** is high, data passes through to the outputs. When **LE** goes low, data is latched.  
- The **OE** pin controls the output state (high-impedance or active).  

### **Features:**  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Transparent Latching:** Data transfers while LE is high.  
- **Wide Operating Voltage:** Compatible with 3.3V and 5V systems.  
- **High Noise Immunity:** Typical noise margin of 0.9V (at 5V).  
- **Pb-Free and RoHS Compliant.**
