The onsemi 74ACT521SC is an 8-bit identity comparator from the 74ACT series. This device facilitates direct comparison of two 8-bit data words, outputting an active low signal when both words are identical (A=B). Designed for surface mount applications, it utilizes a 20-SOIC package. Key electrical characteristics include a supply voltage range of 4.5V to 5.5V, with typical output drive capabilities of 24mA for both high and low states. The quiescent current is a minimal 4 µA. Maximum propagation delay is specified at 10ns under a 5V supply and 50pF load capacitance. This component finds application in digital logic, data routing, and control systems across various industrial sectors.
