SN74AC573DW Description

The SN74AC573DW from Texas Instruments is a high-performance 8-bit transparent D-type latch designed for surface-mount applications. Packaged in a 20-SOIC tube, this IC operates within a 2V to 6V supply voltage range, making it versatile for both 3.3V and 5V systems. With a propagation delay of just 2.5ns and symmetrical 24mA output drive (high and low), it ensures fast, reliable data transfer in digital systems. The device is ROHS3 compliant and REACH unaffected, meeting stringent environmental standards. Its 74AC series technology offers improved speed and power efficiency over older TTL logic families.
