Description and Introduction

OCTAL D-TYPE LATCH WITH 3 STATE OUTPUT (NON INVERTING) The M74HC373TTR is a high-speed 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:** D-Type Transparent Latch  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 2V to 6V  
- **High Noise Immunity:** CMOS technology  
- **Low Power Consumption:** Typically 4µA at 5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TSSOP-20  

### **Descriptions:**  
- The M74HC373TTR is designed for bus-oriented applications.  
- It features eight transparent latches with 3-state outputs for bus interfacing.  
- When the Latch Enable (LE) input is high, the Q outputs follow the data (D) inputs.  
- When LE is low, the data is latched.  
- The Output Enable (OE) input controls the 3-state outputs.  

### **Features:**  
- **High-Speed Operation:** tPD = 13 ns (Typ.) at VCC = 5V  
- **Balanced Propagation Delays**  
- **Low Input Current:** 1 µA (Max.)  
- **Compatible with TTL Levels**  
- **ESD Protection:** HBM > 2000V, MM > 200V  
- **Wide Operating Voltage Range** (2V to 6V)  

This device is commonly used in memory address latching, data buffering, and I/O port expansion in digital systems.
