SN74ABT16821DGGR - 20-Bit Bus Interface Flip-Flops from Texas Instruments

The SN74ABT16821DGGR is a high-performance, 20-bit bus interface flip-flop designed by Texas Instruments for use in a variety of digital systems. This integrated circuit is part of the ABT family, known for its advanced biCMOS technology, which provides a perfect balance between speed and power consumption. The device is specifically crafted to deliver high-speed operation while maintaining low power dissipation, making it an ideal choice for interfacing with bus-oriented systems.

This flip-flop features two sets of ten flip-flops with separate clock (CLK) and clear (CLR) inputs for each section. It is capable of storing 20 bits of data, which can be output on the 20-bit bus. The SN74ABT16821DGGR operates with a 3-state output, which allows for connection to a bus-structured system without the need for additional buffering. This feature provides high drive capability and minimizes the need for external components, thus simplifying design and reducing overall system cost.

The device comes in a 48-pin TSSOP (Thin Shrink Small Outline Package) type, designated by the DGGR suffix, which is suitable for surface-mount technology (SMT) and offers a compact footprint for space-constrained applications. The SN74ABT16821DGGR is designed to work with a 5V power supply, making it compatible with many existing logic systems and straightforward to integrate into a wide range of digital applications.

Key features of the SN74ABT16821DGGR include its high-speed data transfer capabilities, low power consumption, and the robustness provided by the latch-up performance that exceeds 250 mA per JESD 17 standard. Additionally, it has an operating temperature range of -40°C to 85°C, ensuring reliable performance across various environmental conditions.

Whether you are developing data storage, communication systems, computers, or any other application requiring a high-speed and reliable bus interface, the SN74ABT16821DGGR from Texas Instruments is an excellent choice for your design needs.
