N74F521D,602

Comparators Overview

The N74F521D,602 is an 8-bit identity comparator from the NXP 74F series. It features active low outputs indicating equality between two 8-bit inputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports surface mount installation in a 20-SOIC package with a width of 0.295 inches (7.50mm). It functions reliably across an ambient temperature range of 0°C to 70°C.

Comparators Feature Summary

• Performs 8-bit magnitude comparison to determine input equality
• Provides active low output signals for identity detection
• Compatible with standard 5V logic supply rails

Comparators Applications

• Digital system address matching
• Data validation circuits
