Description and Introduction

OCTAL D-TYPE LATCH WITH 3 STATE OUTPUT (NON INVERTING) The M74HCT373 is a high-speed CMOS octal D-type transparent latch with 3-state outputs, manufactured by STMicroelectronics.  

### **Key Specifications:**  
- **Logic Family:** HCT (High-speed CMOS, TTL compatible)  
- **Number of Bits:** 8 (Octal)  
- **Latch Type:** Transparent (data passes through when enable is high)  
- **Output Type:** 3-state (high, low, high-impedance)  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Input Voltage (TTL Compatible):** 0V to VCC  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Propagation Delay (Max):** 24ns at 4.5V  
- **Output Current (High/Low):** ±6mA  

### **Descriptions and Features:**  
- **3-State Outputs:** Allows multiple devices to share a common bus.  
- **TTL Compatibility:** Direct interface with TTL levels (5V operation).  
- **High Noise Immunity:** CMOS technology ensures low power consumption and noise resistance.  
- **Transparent Latch Operation:** Data is latched when the Latch Enable (LE) is high.  
- **Output Enable (OE) Control:** Disables outputs when OE is high (high-impedance state).  
- **Wide Operating Voltage:** Supports standard 5V logic systems.  
- **Low Power Consumption:** Typical ICC of 4µA (static).  

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