SN74F521NS TI 8-Bit Identity Comparator | 20-SO | 4.5V-5.5V, 8-Bit

Product Overview

The SN74F521NS is a high-speed 8-bit identity comparator from Texas Instruments, designed for digital systems requiring fast and accurate data comparison. Fabricated with advanced Schottky technology, this device compares two 8-bit words (P and Q) and provides a low-level output when they are equal. It operates over a wide supply voltage range of 4.5V to 5.5V, making it suitable for TTL logic systems. The 20-SO package offers a compact surface-mount solution for space-constrained applications.
