Product Description

The SN74AS648DWR features eight D-type flip-flops that act as a storage register as well as a bus transceiver with 3-state outputs. This dual-functionality allows for the bidirectional transfer of data on the bus and the temporary storage of that data, providing flexibility and efficiency in data handling. The device operates with a supply voltage range of 4.5V to 5.5V, making it compatible with TTL power levels.

Designed for use in systems that require high-speed and robust data transfer, the SN74AS648DWR is capable of driving heavily loaded buses with capacitances up to 15 pF. Its high drive current is particularly useful in bus-terminated applications. The 3-state outputs ensure that multiple chips can be connected to the same bus without interference, as long as only one is enabled at a time.

Available in a surface-mount SOIC-20 package, the SN74AS648DWR is suitable for compact designs where space is at a premium. Its wide operating temperature range from -40°C to +85°C ensures reliable performance in a variety of environmental conditions.

Whether for use in microprocessor or memory interface circuits, data communication systems, or any application requiring high-speed and reliable data transfer and storage, the SN74AS648DWR from Texas Instruments stands out as a robust and versatile component.
