TI CD74AC573EX

Harris AC/ACT Series advanced high-speed CMOS ICs cover a wide range of logic types with performance and speed comparable to FAST, AS (Advanced Schottky), and S (Schottky) bipolar types, while significantly reducing power dissipation in logic operations. The series includes two basic logic families: the CD54/74ACTXXX series, featuring TTL input voltage level compatibility with reduced power consumption compared to FAST, AS, and S bipolar logic family types; and the CD54/74ACXXX series, featuring CMOS input voltage level compatibility that provides enhanced system performance (improved system noise margins) at speeds similar to FAST, AS, and S logic family types. The AC/ACT series encompasses a variety of octal buffers, latches, flip-flops, transceivers, and more, with both ACT and AC families offering over 100 circuit types. Compared to conventional high-current bipolar FAST and AS logic types, Harris AC and ACT types offer many significant advantages, enabling drop-in replacement of bipolar types in both existing and new equipment designs at frequencies up to 100MHz. The advanced CMOS high-speed products are manufactured using advanced small-geometry CMOS processes and design rules to meet specified high-speed and high output drive current requirements, while suppressing the high switching current transients associated with high-speed designs.
