SN74F521NSR TI Comparator | 20-SO | 8-Bit, Identity, Active Low

Product Overview

The SN74F521NSR from Texas Instruments is an 8-bit identity comparator designed for high-speed digital systems. It compares two 8-bit words (P and Q) and provides an output indicating whether they are equal. The device features active-low outputs and is available in a 20-pin SO package. It operates from a 4.5V to 5.5V supply and offers typical propagation delays of 10ns, making it suitable for high-performance applications.
