The onsemi 74ACT521SJ is an 8-bit identity comparator from the 74ACT series. This device offers active low outputs that indicate when the two 8-bit data inputs (A and B) are equal (A=B). Designed for surface mounting, it utilizes a 20-SOIC package for efficient board integration. Key electrical specifications include a wide supply voltage range of 4.5V to 5.5V, with a quiescent current of only 4 µA. The comparator exhibits a maximum propagation delay of 10ns at 5V with a 50pF load capacitance. Output drive capability is rated at 24mA for both high and low states. This component finds application in various digital systems, including data routing, error detection, and bus comparison.
