Description and Introduction

8-BIT MAGNITUDE/IDENTITY COMPARATORS The SN74LS685N is a 8-bit magnitude comparator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** 8-bit Magnitude Comparator  
- **Technology:** LS (Low-Power Schottky)  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP (Plastic Dual In-line Package)  
- **Pin Count:** 20  
- **Output Type:** Active Low, Open Collector  
- **Propagation Delay:** Typically 30ns  
- **Power Dissipation:** 85mW (typical)  

### **Descriptions:**  
The SN74LS685N compares two 8-bit binary or BCD words and provides outputs indicating whether one word is greater than, less than, or equal to the other. It features cascading inputs for expansion to larger word sizes.  

### **Features:**  
- **8-bit Comparison:** Compares two 8-bit words (A and B).  
- **Three Outputs:**  
  - **P > Q** (A > B)  
  - **P = Q** (A = B)  
  - **P < Q** (A < B)  
- **Cascading Inputs:** Allows expansion to larger word lengths.  
- **Open-Collector Outputs:** For wired-AND applications.  
- **Low Power Consumption:** LS technology ensures reduced power usage.  
- **TTL-Compatible Inputs:** Works with standard TTL logic levels.  

This device is commonly used in digital systems for arithmetic operations, control logic, and decision-making circuits.

Alternative Part Number

  • DM74LS685N --: Same 74LS685 magnitude comparator function in a standard DIP package, pin-compatible with the original.
  • MC74LS685N --: Equivalent 74LS685 comparator from a different series prefix, same logic function and DIP pinout.
  • SN74LS682N --: Related 74LS comparator family device with similar function; verify pinout and electrical differences before substitution.
  • 74LS685N --: Standard 74LS685 comparator in a DIP package with equivalent logic function and pinout, offered by a major alternate supplier.
