SN74HC574DWRG4 Octal Edge-Triggered D-Type Flip-Flops with 3-State Outputs

The SN74HC574DWRG4 from Texas Instruments is a high-performance, octal edge-triggered D-type flip-flop integrated circuit, designed for use in a wide range of digital applications. This device is part of the 74HC series, which are known for their high-speed CMOS logic operations. The SN74HC574DWRG4 features eight D-type flip-flops with 3-state outputs, making it ideal for bus-oriented applications.

Each flip-flop has independent data (D), clock (CLK), and output enable (OE) inputs, with a Q output for each flip-flop. The flip-flops capture the state of their individual D-inputs on the rising edge of the clock signal, and the data is then available at the Q outputs. When the output enable (OE) is low, the outputs are active and reflect the data stored in the flip-flops. However, when OE is high, the outputs are in a high-impedance state, which allows for the outputs to be disconnected from the bus line, preventing potential bus contention.

The SN74HC574DWRG4 has a wide operating voltage range of 2V to 6V, which allows for compatibility with TTL levels and the ability to interface with a variety of other logic families. This makes it a versatile choice for creating a reliable and efficient data storage and transfer system in your digital circuitry.

This device is supplied in a wide-body SOIC (DW) package with 20 pins, which is designed to optimize the thermal performance and minimize the PCB space required. The SN74HC574DWRG4 is characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide range of environmental conditions.

Whether you're designing data buses, buffer registers, or other digital systems requiring high-speed, reliable flip-flops with 3-state outputs, the SN74HC574DWRG4 from Texas Instruments is an excellent choice that combines performance, versatility, and quality.
