Product Description

The MC74HCT574AN is a robust octal flip-flop that captures the data present on its D inputs on the rising edge of the clock (CLK) input. Once captured, the data is held in the flip-flop and can be output on the Q outputs in a non-inverting fashion. The 3-state outputs are controlled by the Output Enable (OE) input. When OE is low, the outputs are active and reflect the data held in the flip-flops. When OE is high, the outputs are in a high-impedance state, effectively isolating them from the bus.

This feature allows for the direct connection of multiple outputs to a bus without the need for interface or pull-up components. The MC74HCT574AN is designed for use in applications requiring high-speed data storage and transfer, such as computers, communication systems, and advanced microprocessor systems.

ON Semiconductor's commitment to quality ensures that the MC74HCT574AN meets the stringent requirements for reliable operation in a wide range of environmental conditions. The device is available in a standard 20-pin DIP package, making it easy to integrate into various circuit designs.
