SN74ALVCH16821DLR - Texas Instruments

The SN74ALVCH16821DLR from Texas Instruments is a high-performance, 20-bit flip-flop with 3-state outputs designed to be used in a wide array of digital applications. This integrated circuit (IC) is part of the advanced low-voltage CMOS (ALVC) family, which is known for its low power consumption and high-speed operation.

With its dual 10-bit flip-flops, the SN74ALVCH16821DLR is ideal for temporary storage of data, acting as a buffer between two buses or simply as a means to increase the word length of a data processing system. Each flip-flop is clocked by a common clock input (CLK) and can be set or reset by a common set/reset input (SRT). This allows for synchronous control of all bits through a single command, ensuring data integrity and simplifying the timing design of your system.

The 3-state outputs provide the capability to place the output in a high-impedance state. This feature is particularly useful in bus-oriented systems where multiple drivers can share the same bus lines without the risk of bus contention, as only one driver is enabled at a time. The output-enable (OE) input controls the transition between active and high-impedance states, thus allowing seamless integration with other components in the system.

Designed with the latest technology, the SN74ALVCH16821DLR operates at a voltage range of 2.3V to 3.6V, which makes it compatible with both 3.3V and 2.5V logic levels, providing the flexibility needed for multi-voltage systems. Moreover, the device features balanced propagation delays and transition times, which contribute to its reliable high-speed performance.

Encased in a 56-pin SSOP (Shrink Small Outline Package), the SN74ALVCH16821DLR offers a compact footprint that is suitable for space-constrained applications. Its robust design ensures that it meets the stringent requirements of industrial temperature ranges, making it a versatile choice for both commercial and industrial environments.

Whether you are designing data storage, communication interfaces, or complex digital systems, the SN74ALVCH16821DLR from Texas Instruments provides a reliable and efficient solution that engineers and designers can count on for high-speed and low-power applications.
