Description and Introduction

Octal D-type Transparent Latches with 3-state Outputs The SN74S373J is a part manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** SN74S373J  
- **Type:** Octal Transparent Latch with 3-State Outputs  
- **Technology:** Schottky TTL (S-Series)  
- **Package:** 20-Pin Ceramic DIP (Dual In-Line Package)  
- **Operating Voltage:** 5V (Standard TTL)  
- **Output Type:** 3-State (High, Low, High-Impedance)  
- **Number of Bits:** 8 (Octal)  
- **Latch Type:** Transparent (Data passes through when latch enable is high)  
- **Propagation Delay:** Typically 7ns (varies with conditions)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial grade)  

### **Descriptions:**  
The SN74S373J is an octal transparent latch with 3-state outputs, designed for bus-oriented applications. It allows data to be stored or passed through when the latch enable (LE) input is active. The outputs can be placed in a high-impedance state using the output enable (OE) input, making it suitable for shared bus systems.  

### **Features:**  
- **Octal D-Type Transparent Latches** with 3-state outputs  
- **Schottky-clamped** for high performance  
- **Bus-structured pinout** for easy PCB layout  
- **Latch Enable (LE) input** controls data storage  
- **Output Enable (OE) input** for 3-state control  
- **Wide operating voltage range** (4.75V to 5.25V)  
- **High-speed operation** (typical propagation delay of 7ns)  
- **Compatible with TTL logic levels**  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Octal D-type Transparent Latches with 3-state Outputs

Alternative Part Number

  • DM74S373N --: Same 74S octal D-type transparent latch function with tri-state outputs, pin-compatible DIP package, from a different series prefix.
  • N74S373N --: Equivalent 74S373 octal latch in DIP, same logic family and pinout, different manufacturer naming.
  • MC74S373N --: Pin-compatible 74S373 octal transparent latch with tri-state outputs, suitable drop-in replacement in DIP.
  • 74S373PC --: Same 74S octal D-type transparent latch function in a DIP package, pin-compatible and directly interchangeable.
