SN74F521DWR TI Comparators | 20-SOIC | 8-Bit Identity, Active Low

Product Overview

The SN74F521DWR from Texas Instruments is a high-speed 8-bit identity comparator designed for digital systems requiring fast and accurate comparison of two 8-bit words. Fabricated with advanced bipolar technology, this device offers propagation delays as low as 8 ns, making it suitable for high-performance computing and communication systems. The comparator provides an active-low output (A=B) that goes low when the two input words are equal. It operates over a wide supply voltage range of 4.5V to 5.5V and is characterized for operation from 0°C to 70°C. The 20-SOIC package ensures compact footprint and ease of assembly in surface-mount applications.
