Additional Details

The 54AC574DMQB is typically packaged in a ceramic DIP (Dual In-line Package). The 'QB' suffix indicates that it meets specific quality and reliability requirements, often associated with military or high-reliability applications. It operates with a supply voltage of 5V and features a typical propagation delay of a few nanoseconds. The 3-STATE outputs can be disabled, allowing multiple devices to share the same bus lines.
