SN74ALS521NSR TI Identity Comparator | 20-SO | 8-Bit, 24mA Output

Product Overview

The SN74ALS521NSR is a high-performance 8-bit identity comparator from Texas Instruments, designed for high-speed digital systems. It compares two 8-bit words (P and Q) and provides a single output (P=Q) that goes low when the two inputs are equal. Fabricated with advanced Schottky-clamped ALS technology, it offers a typical propagation delay of 15 ns and low power consumption of 45 mW. The device is available in a 20-pin SO package, making it suitable for space-constrained applications.
