74ls688 8-bit Magnitude Comparators

74LS682, 74LS684, and 74LS688 – 8-Bit Magnitude Comparators

The 74LS682, 74LS684, and 74LS688 are 8-bit magnitude comparators designed for comparing two 8-bit binary or BCD (Binary Coded Decimal) words. These devices provide the ability to evaluate the magnitude relationships between two data inputs, with outputs that indicate whether the inputs are equal, greater than, or less than each other.

Key Features:

• 8-Bit Magnitude Comparison: These comparators are capable of comparing two 8-bit binary or BCD words, making them ideal for high-speed digital logic applications that require data comparison.
• Output Pins:
  • P = Q: Indicates when the two 8-bit words are equal.
  • P > Q (Available in LS682 and LS684 models): Indicates when the first input is greater than the second.
• Totem-Pole Output: All models feature totem-pole outputs for improved drive capabilities and faster switching times.
• LS682 Specific Feature: The LS682 includes a 20 kΩ pull-up resistor on the Q inputs, which makes it suitable for analog or switch data comparisons, improving compatibility with analog input devices.

Applications:

• Digital Comparisons: Used for comparing numerical or binary values in applications such as digital systems, microcontrollers, and logic circuits.
• BCD Comparisons: Can be utilized in BCD systems for validating and comparing decimal values in digital electronics.
• Data Validation and Sorting: Ideal for systems that need to verify if data meets specific criteria or to sort information based on magnitude.
• Signal Matching: Can be used for detecting signal levels, voltage comparisons, or detecting matching signals in high-speed circuits.

Package Includes:

• 1 x 74LS682 / 74LS684 / 74LS688 IC

These 8-bit magnitude comparators provide reliable, fast, and accurate comparisons of digital and BCD words, with flexible outputs for various logic systems and applications. Whether for digital or analog comparisons, these ICs are essential components for many high-speed and precision-based electronic projects.
