Each flip-flop captures the D input on the rising edge of the clock and holds it until the next clock edge. This part is typically used in register, counter, and data-latch applications in legacy TTL-based systems — think industrial controllers, test equipment, or retrofits of 1970s–80s board-level designs. The Bulk package designation points to a through-hole ceramic DIP, common in high-reliability or military-temperature-range sockets where socketed replacement is expected.","metaTitle":"74H74DC Dual D Flip-Flop, Positive-Edge Triggered, Active","metaDescription":"74H74DC dual D-type flip-flop, positive-edge triggered, Bulk package.
