SN74ACT534DBRE4 Octal D-Type Flip-Flop with 3-State Outputs

The SN74ACT534DBRE4 from Texas Instruments is a high-performance, octal edge-triggered D-type flip-flop integrated circuit. This device is designed to offer robust and reliable performance in a wide array of digital applications. It is particularly well-suited for the implementation of buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The SN74ACT534DBRE4 features eight D-type flip-flops with 3-state outputs that can interface directly with bus-oriented systems. With a wide operating voltage range from 4.5V to 5.5V, this IC ensures compatibility with industry-standard 5V digital systems. The high drive capability and fast switching speeds make it an excellent choice for interfacing with high-speed microprocessors and memory systems.

Each flip-flop is equipped with a direct clear input and a direct output enable. The clear input allows for the synchronization of the setup in systems that require precise timing control, while the output enable feature adds flexibility by allowing the user to put the outputs into a high-impedance state. This is particularly useful in applications that require shared data lines or multiplexing.

The device comes in a 20-pin SSOP (DB) package, making it space-efficient for PCB design. The pinout arrangement is designed for optimal signal routing, which minimizes the possibility of cross-talk and ensures signal integrity, even in environments with high switching activity.

In summary, the SN74ACT534DBRE4 flip-flop offers high-speed operation, robust performance, and 3-state outputs, making it a versatile component for digital systems. Its compatibility with 5V systems, coupled with its wide operating temperature range, ensures that it can meet the demands of a variety of applications, from simple buffers to complex data storage and transfer systems.
