Flip-flops or bistable circuits are a crucial component of digital logic circuits, providing the vital function of circuit memories and data capture by allowing a circuit to store and recall values, and are the basis of many significant types of computing machines. The CY74FCT574TSOCTE4 Flip-Flop is one such device, providing eight independent positive-edge triggered D-type flip-flops with 3-STATE outputs, integrated into a single package.

The CY74FCT574TSOCTE4 Flip-Flop is a high-speed, “glue” logic IC offering over-voltage tolerant inputs, hysteresis on all inputs, and designed to withstand bus contention. It has both low voltage, single-ended and high voltage, differential inputs, and is specified to function over a -40°C to +85°C temperature range. Outputs can reach speeds of up to 133 MHz and are TTL compatible.

The CY74FCT574TSOCTE4 Flip-Flop offers multiple advantages for digital logic design. The 3-STATE function allows the IC to be used in bus-oriented systems where the address and data lines are multiplexed. Each active-high input features hysteresis, so it will operate properly with noisy signals or at frequencies beyond its rated speeds. The output includes two complementary levels plus a high-impedance state, so that the device can be cascaded with other ICs, A/B multi-plexers, or optically-coupled interfaces.

The CY74FCT574TSOCTE4 Flip-Flop operates according to a basic edge-triggered logic system, with different related input and output concepts. The “clock” signal determines when the data should be recorded. An edge (or transition pulse) at the clock input triggers the device and inputs the “data” signal present at that time. The output (Q) of the flip-flop stores this data until the rising/falling edge of the clock signal changes the output state, or for as long as the device is powered on. The device has “clear” and “preset” lines allowing single-precision triggering and control of the outputs.

The CY74FCT574TSOCTE4 Flip-Flop is available in several packages including the 20-lead plastic SSOP (Shrink Small-Outline Package) and the 20-pin plastic DIP (Dual Inline Package). This shows its widespread applications in a variety of environments. It is ideal for high-speed applications requiring large handle capacitive loads, optically-coupled isolation, address and data bus multiplexing, and multiplexed line drivers. The device can also be used in automobiles, where its over-voltage protection on input and output lines is particularly beneficial. It is also often used in communication systems and computer systems.

The CY74FCT574TSOCTE4 Flip-Flop is an impressive device with versatile uses. Its multiple input types, hysteresis and 3-STATE output capabilities make it highly applicable for modern digital logic design. Especially where tight timing requirements, noise immunity, or isolated drivers are needed, the CY74FCT574TSOCTE4 Flip-Flop is an ideal choice.
