74173 4-Bit D-Type Register Logic IC

The 74173 is a TTL logic IC that implements a 4-bit D-type register with three-state outputs.
It stores parallel data inputs and updates the output on an active clock transition.
The device operates from a single 5 V supply and is compatible with standard TTL logic levels.
Its tri-state outputs allow direct connection to shared data buses.
Typical applications include data storage, bus interfacing, temporary registers, and digital control systems.
