Additional Details:

The 74F243PC operates from a 5V power supply and is typically available in a plastic dual-in-line package (PDIP). Key specifications include a propagation delay of approximately 4ns and a supply current of roughly 40mA. The three-state outputs enable the device to be connected directly to a bus without loading it when the device is disabled. The direction of data flow is controlled by a separate input pin. The 74F243PC is commonly used in computer systems, communication equipment, and industrial control systems to facilitate efficient and reliable data transfer. Because Rochester Electronics stocks this part, legacy systems are guaranteed to have access to the part to maintain production or service existing equipment.
