Description and Introduction

OCTAL D-TYPE LATCH WITH 3-STATE OUTPUT (NON INVERTING) The M74HC533B1R is a high-speed CMOS octal D-type transparent latch with 3-state outputs, manufactured by STMicroelectronics.  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Number of Bits:** 8 (Octal)  
- **Latch Type:** Transparent  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** CMOS technology  
- **Low Power Consumption:** Typical ICC of 4µA at 25°C  
- **High-Speed Operation:** tPD = 13ns (typ.) at VCC = 4.5V  
- **Output Drive Capability:** 10 LSTTL Loads  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** SO-20  

### **Descriptions:**  
The M74HC533B1R is designed for bus-oriented applications where multiple outputs need to be controlled. It features transparent latches, meaning the outputs follow the data inputs while the latch enable (LE) is high. When LE goes low, the data is latched. The 3-state outputs allow connection to a common bus.  

### **Features:**  
- **Octal D-type transparent latch**  
- **3-state outputs for bus interfacing**  
- **Inverting outputs**  
- **Balanced propagation delays**  
- **Wide operating voltage range (2V to 6V)**  
- **Compatible with TTL levels**  
- **ESD protection (HBM > 2000V, MM > 200V)**  
- **Latch-up immunity (JESD78D Class II Level A)**  

This device is suitable for applications such as memory address latching, I/O port control, and bus buffering.
