The 54ACT574FMQB is a high-speed, octal D-type flip-flop integrated circuit designed and manufactured by Texas Instruments. This device is part of the 54ACT family, known for its advanced high-speed CMOS logic operating in the military temperature range. The 54ACT574FMQB is encapsulated in a durable, military-grade flat package, ensuring its reliability and performance under extreme conditions.

Featuring a set of eight edge-triggered D-type flip-flops with a common clock (CLK) and output enable (OE) inputs, this IC is ideal for temporary storage of data, acting as a buffer or as a delay element in digital circuits. The flip-flops capture the state of their individual D inputs on the rising edge of the clock, making the device suitable for applications requiring synchronous data capture and transfer.

Each flip-flop has a separate D input and Q output, providing flexibility in application. The OE input controls the tri-state outputs, which can be placed in a high-impedance state. This feature allows for multiple devices to share a common data bus without the risk of bus contention.

Key specifications of the 54ACT574FMQB include:

• Operates from a 4.5V to 5.5V supply voltage, accommodating standard TTL power levels.
• Capable of driving 24mA outputs, providing good current sinking capability for driving LEDs or other loads.
• Features a military temperature range from -55°C to +125°C, ensuring operation in harsh environments.
• Guaranteed 4000V minimum ESD protection, ensuring the device's resilience against electrostatic discharge events.

With its robust design and advanced features, the 54ACT574FMQB is a versatile component for military and aerospace applications, as well as other high-reliability systems where data integrity and device ruggedness are paramount. Texas Instruments' commitment to quality makes the 54ACT574FMQB a reliable choice for designers looking to incorporate a dependable octal flip-flop in their digital logic designs.
