74ABT899CQC

The 74ABT899CQC is a Logic - Specialty Logic chip from NXP Semiconductors. It is a family of high-speed CMOS devices that serve as a single bit, two-to-four line multiplexer/demultiplexer, including priority encoding/decoding. The device\'s versatile data handling capabilities make it ideal for a wide range of applications. It operates in both single supply (2.0V to 6.0V) and dual supply environments.

Application Field and Working Principle

The 74ABT899CQC is designed for high speed data processing applications, such as sequencers and telecommunications. The device is ideal for multiplexing and demultiplexing applications where fast logic levels and wide supply voltage ranges are required.

The device operates on two logic levels, with HIGH and LOW logic values corresponding to VDD and VSS respectively. It has four input lines, each of which can be associated with one of two data sets. The device also has two output lines, each of which can be associated with one of two data sets. The two output lines are enabled by two control lines, the O1 and O2 control lines.

When the O1 control line is LOW, the data set associated with the first input line is output on the first output line. Similarly, when the O2 control line is LOW, the data set associated with the second input line is output on the second output line. The device also features priority encoding and decoding logic, allowing it to prioritize data in multiplexing applications and decode received data in demultiplexing applications.

The device features very low propagation delays (8ns max, over temperature) and very low power dissipation (2.8mA max at 3.3V). This makes it a suitable choice for high speed, low power data applications. Additionally, the device features both non-inverting and inverting outputs, allowing for direct interfacing with both CMOS and TTL logic devices.

Overall, the 74ABT899CQC is a versatile, high-speed Logic - Specialty Logic chip that is ideal for a wide variety of data processing applications. It is suitable for both single and dual supply environments and provides low power, low propagation delay operation, making it a great choice for high speed data processing applications.
