SN74AC573DBR Description

The SN74AC573DBR from Texas Instruments is a high-performance 8-bit transparent D-type latch designed for surface-mount applications. Part of the 74AC series, it operates within a 2V to 6V supply voltage range, making it versatile for mixed-voltage systems. This IC features 3-state outputs, allowing multiple devices to share a common bus without interference. With a propagation delay of just 2.5ns and symmetrical 24mA output drive (sink/source), it ensures fast, reliable signal transmission in high-speed digital circuits. Packaged in a 20-pin SSOP (Shrink Small Outline Package) and delivered in Tape & Reel (TR), it is optimized for automated assembly processes.
