SN74ABT821ADWRG4: 10-Bit Bus Interface Flip-Flops with 3-State Outputs

The SN74ABT821ADWRG4 is a high-performance integrated circuit designed and manufactured by Texas Instruments, a leader in semiconductor innovation. This particular device is part of the ABT family, known for its advanced biCMOS technology that delivers the optimal balance between speed and power consumption, making it a great choice for interfacing with 10-bit buses in a wide range of digital applications.

Key features of the SN74ABT821ADWRG4 include its 10 flip-flops with 3-state outputs, which allow for convenient connection to a bus or data lines. This makes it perfect for systems that require temporary storage of data or need to transfer data from one part of the system to another without interference. The 3-state outputs ensure that multiple devices can share the same bus without conflict, as they can be put into a high-impedance state when not in use.

Another significant advantage of this product is its edge-triggered D-type inputs, which capture data on the rising edge of the clock signal, providing precise timing and control. The device also features a direct clear (CLR) input, which can be used to reset all flip-flops, ensuring that the system can be quickly initialized or cleared when necessary.

The SN74ABT821ADWRG4 operates over a broad voltage range, with a typical supply voltage of 4.5V to 5.5V, making it versatile for various digital logic levels and compatible with TTL (Transistor-Transistor Logic) environments. Additionally, the device supports a wide operating temperature range, ensuring reliable performance across different environmental conditions.

Housed in a 24-pin SOIC (Small Outline Integrated Circuit) package, the SN74ABT821ADWRG4 is optimized for space-saving designs, allowing for a more compact and efficient PCB layout. This package is also well-suited for automated assembly processes, reducing manufacturing time and costs.

Overall, the SN74ABT821ADWRG4 from Texas Instruments stands out as a reliable and high-quality component for designers and engineers looking to build sophisticated digital systems requiring robust bus interface capabilities.
