onsemi's 74AC521SCX is an 8-bit identity comparator from the 74AC series. This device features active-low outputs and is designed for applications where precise digital signal comparison is critical. The comparator's output logic, A=B, activates when all eight input bits match. With a maximum propagation delay of 8.5ns at 5V and 50pF, it supports high-speed operation. The device operates across a voltage supply range of 2V to 6V and consumes a quiescent current of only 4 µA. Output drive capability is 24mA for both high and low states. The 74AC521SCX is housed in a 20-SOIC (0.295" width) surface-mount package, making it suitable for automated assembly processes. This component finds utility in various industrial and consumer electronics, including data processing and control systems. It is supplied in Tape & Reel packaging.
