Description and Introduction

Octal Transparent D-Type Latches With 3-State Outputs The SN74HC373DWR is a high-speed octal transparent latch with 3-state outputs, manufactured by Texas Instruments.  

### **Key Specifications:**  
- **Logic Type:** Octal Transparent Latch  
- **Output Type:** 3-State  
- **Number of Bits:** 8  
- **Voltage Supply Range:** 2V to 6V  
- **High-Level Output Current:** -7.8mA  
- **Low-Level Output Current:** 7.8mA  
- **Propagation Delay Time:** 15ns at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SOIC-20 (DWR)  

### **Descriptions:**  
The SN74HC373DWR is designed for bus-oriented applications, allowing data to be latched when the latch enable (LE) input is high. When LE is low, the outputs follow the data inputs. The output enable (OE) input controls the 3-state outputs, enabling high-impedance when OE is high.  

### **Features:**  
- **3-State Outputs:** Allows bus connection and isolation  
- **Wide Operating Voltage:** 2V to 6V  
- **High-Current Outputs:** Drive up to 15 LSTTL loads  
- **Low Power Consumption:** CMOS technology  
- **Balanced Propagation Delays**  
- **ESD Protection:** Exceeds 2000V per JESD 22  

This latch is commonly used in memory address latching, I/O port expansion, and data buffering applications.
