The LVT574 and LVTH574 are high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-STATE outputs for bus-oriented appli- cations.
The Fairchild 74LVT574 and 74LVTH574 are low‑voltage octal D‑type flip‑flops with three‑state outputs, offering high‑speed, low‑power operation and an optional bus‑hold feature for bus‑oriented applications.
These devices are offered in several small‑outline packages (SOIC, SOP, SSOP, TSSOP) and operate from 0.5 V to 4.6 V supply voltage, with input voltage up to 7 V. They provide high‑level output current up to –32 mA and low‑level output current up to 64 mA, with typical power‑supply currents of 0.18 mA (outputs high) and 5 mA (outputs low). Detailed electrical parameters, pin assignments, and ordering information are included.
