SN54HC174, SN74HC174 are monolithic positive-edge-triggered D-type flip-flops with a direct clear (CLR) input. It is applicable to buffer/storage registers, shift registers and pattern generators. The product has plastic small-outline (D) and ceramic flat (W) packages, ceramic chip carriers (FK), and standard plastic (N) and ceramic (J) 300-mil DIPs options.
This datasheet describes the SN54HC174 and SN74HC174 hex D‑type flip‑flops with a clear (CLR) input. It includes package options, pin‑out diagrams for D, J, N, and W packages, functional tables, and application examples such as buffer/storage registers and shift registers.
The document also lists absolute maximum ratings, recommended operating conditions, electrical and timing characteristics, switching performance, and a detailed parameter measurement section. An important notice at the end outlines warranty, usage restrictions, and liability information for TI semiconductor products.
