SN74LVC574APWR Texas Instruments

The SN74LVC574APWR is an octal (8-bit) D-type flip-flop with tri-state outputs from Texas Instruments. Each flip-flop has independent data, set, reset, and clock inputs and Q and Q_bar outputs. The outputs are enabled by the output-enable (OE) input and, when an output is enabled, the corresponding Q and Q_bar outputs will become active. All data inputs indicate the levels of the data to be stored in the flip-flop on the next high-to-low transition of the clock input following the low-to-high transition of the enable signal. When the OE is disabled, the outputs become high-impedance states. The device is manufactured in a variety of packages, including a PowerPAD™ low-profile thin shrink small-outline package (PWP) and is ideal for use in applications where board space is at a premium. It features high-performance Schmitt trigger clock inputs, which allow for noise immunity and stable clock operation over extended period of time. It is capable of operating from 1.65 V to 5.5 V over the full industrial temperature range of -40 °C to 125 °C, and is designed to be fully compatible with TTL logic circuits.
