The 74AC175 • 74ACT175 Quad D-Type Flip-Flop is a high-speed quad D-type flip-flop. The device is useful for general flip-flop requirements where clock and clear inputs are common. The information on the D-type inputs is stored during the LOW-to-HIGH clock transition. Both true and complemented outputs of each flip-flop are provided. A Master Reset input resets all flip-flops, independent of the Clock or D-type inputs, when LOW.
The 74AC175 and 74ACT175 are high‑speed quad D‑type flip‑flops with common clock and master‑reset inputs. They store data on the low‑to‑high clock transition and provide both true and complemented outputs for each flip‑flop. The devices feature TTL‑compatible inputs, edge‑triggered operation, and a master reset that forces all outputs low regardless of clock or data inputs.
Key features include 24 mA source/sink output capability, a wide supply voltage range, and operation over a temperature range from –65 °C to +150 °C. The datasheet lists multiple package options (SOIC, SOP, TSSOP, PDIP) and provides detailed electrical characteristics, timing parameters, and physical dimensions.
