74ABT899CQCX is a high-speed octal buffer/line driver and it is well suited foremployment in high-performance memory and bus-oriented systems. It operatesroughly twice as fast as a typical octal buffer used in applications such as personal computers.Designed specifically to run at high speeds in both the NTSC and PAL televisionstandard, it is also capable of operating in both TTL and Schottky logic. It issuitable for use in data bus, address bus and I/O buses.In operation, 74ABT899CQCX ensures fast propagation delay and low powerdissipation. It also provides excellent noise immunity and is optimized forboth reducing ringing and providing minimum crosstalk between adjacent outputpins.74ABT899CQCX applications encompass a wide range of fields. They arecommonly used in DLP projectors, HDTV digital cable systems, modemcommunications, logic line drivers, and bus transceivers. Its octal high linedrivers are also used in portable computing devices, digital audio/videodistribution systems, and storage area networks (SAN).Due to its speed, low power, and noise immunity, the 74ABT899CQCX is oftenused to interface analog systems to digital systems. Its noise immunity isparticularly useful in these applications, where it helps to reduce crosstalkand ringing.The working principle of 74ABT899CQCX is a combination of two factors:Quad CMOS Technology and Bus Oriented design. The Quad CMOS Technology,combined with Bus Oriented design, allows the device to function in a veryhigh speed, low-power state.Quad CMOS Technology is a high-speed semiconductor technology whichenables the device to operate at high speed while keeping the powerconsumption and power dissipation to a minimum. This technology is used in74ABT899CQCX to achieve a maximum propagation delay of 8 nanoseconds andlow power dissipation of 1.5 watts.Bus Oriented design makes the device well-suited for applicationsinvolving the transfer of data in large intervals. Bus Oriented designfacilitates the transfer of larger bits of data without degradation ofsignal integrity. It also results in a much more efficient data transferprocess by reducing the number of cycles needed to transfer large amounts ofdata.In conclusion, 74ABT899CQCX is a high-speed octal buffer/line driverwhich is ideal for high-speed applications such as DLP projectors, HDTVdigital cable systems, and modem communications. It provides excellent noiseimmunity and achieves a maximum propagation delay of 8 nanoseconds and lowpower dissipation of 1.5 watts. It is well-suited for use in data bus,address bus and I/O buses due to its bus-oriented design.
