Description
Description
The 74173 is a TTL logic integrated circuit designed as a 4-bit D-type register with three-state outputs for efficient data storage and bus interfacing. It allows parallel input data to be stored and transferred synchronously on a clock edge, making it ideal for temporary data storage and digital control systems. Its tri-state outputs enable multiple devices to share the same data bus without interference, making the 74173 essential for microprocessor systems, memory buffering, and bus-oriented digital designs. Operating from a standard 5V TTL supply, it is suitable for educational, industrial, and embedded applications.
