Device identity and logic family
The 74S174PC is a D flip-flop from Texas Instruments' S Series TTL logic family, containing six flip-flops with common clock and clear. It is catalogued under Microcontrollers & Processors (MCU / MPU / DSP) but serves as a standard logic building block for synchronous data storage. The part is supplied in bulk packaging, typical for through-hole DIP devices used in prototyping, repair, or low-volume production.
Lifecycle and compliance status
RoHS compliance is non-compliant, meaning the part contains lead (Pb) above the RoHS exemption thresholds. Plan for exemption handling or a leaded-solder process if this is a new design.
