The 74F521 is an expandable 8-bit identity comparator manufactured by NS. This integrated circuit compares two words, each up to eight bits in length, and outputs a LOW signal when the two words are identical bit for bit. The expansion input, IA=B, also functions as an active LOW enable input, allowing for comparisons of words longer than eight bits.
Key electrical characteristics include a typical comparison speed of 6.5 ns. It operates within a supply voltage range of 4.5V to 5.5V and has an ambient operating temperature range of 0°C to 70°C. The device features active LOW identity output and active LOW enable input.
The 74F521 is available in a 20-pin package, including options like SOIC, SOP, and PDIP. Devices can also be supplied on tape and reel for automated assembly processes.
This comparator is suitable for various digital logic applications requiring word comparison and matching functionalities.
