The HEF40174B is a hex edge-triggered D-type flip-flop with six data inputs (D0 to D5), a clock input (CP), an overriding asynchronous master reset input (MR), and six buffered outputs (O0 to O5).
The HEF40174B is a hex MSI D‑type flip‑flop with buffered outputs, master‑reset and edge‑triggered clock input. The data sheet provides functional diagrams, pin assignments, package options and electrical characteristics.
Key specifications such as propagation delays, maximum clock frequency and input transition times are listed, together with typical application examples like shift registers, buffer/storage registers and pattern generators.
| Package (HEF40174BP(N)) | 16‑lead DIL, plastic |
|---|---|
| Propagation delay (typical) | 48 ns |
| Input transition time | <20 ns |
It is a hex D‑type flip‑flop in the MSI logic family.
The typical propagation delay is 48 ns (with load capacitance factor).
