Product Overview: 74ABT16821ADL-T from NXP

The 74ABT16821ADL-T is a high-performance, 20-bit bus interface flip-flop designed by NXP Semiconductors. This integrated circuit is part of the ABT range, which stands for Advanced BiCMOS Technology, indicating that it is fabricated with a combination of Bipolar and CMOS technology to achieve optimal speed and power characteristics.

Ideal for use in applications where high-speed, low-power operation is crucial, the 74ABT16821ADL-T is particularly well-suited for interfacing with high-speed microprocessors. It can also be used in systems that require the capture and storage of multiple bits of data simultaneously, such as registers or buffers in data paths.

The device features a 20-bit edge-triggered D-type flip-flop with a 3-state output. It is capable of storing 20 bits of input data, which can be viewed or manipulated as a single entity or in smaller segments, providing flexibility for various data handling requirements. The 3-state outputs ensure that additional devices can be connected to the data bus without interference, allowing for bus expansion and the sharing of data lines.

With a wide operating voltage range of 4.5V to 5.5V, the 74ABT16821ADL-T accommodates typical 5V logic levels while providing robust tolerance to supply voltage variations. The device also boasts fast propagation delays and output transition times, making it a reliable choice for high-speed data acquisition and processing tasks.

The 74ABT16821ADL-T is available in a 56-lead SSOP (Shrink Small Outline Package), which is known for its space-saving footprint. The "DL" suffix in the part number indicates that it is offered in a surface-mount package, while the "T" denotes tape and reel packaging, suitable for automated assembly processes.

In summary, the NXP 74ABT16821ADL-T is a versatile and powerful solution for data storage and transfer applications that demand high speed, low power consumption, and reliability. Its advanced technology and thoughtful design make it an excellent choice for a wide range of digital systems.
