SN74ABT2244ADBRG4 Octal Buffer/Line Driver by Texas Instruments

The SN74ABT2244ADBRG4 is a high-performance, octal buffer/line driver designed by Texas Instruments to deliver both high-speed operation and the capability to drive heavily loaded outputs with 25 Ohm series resistance, making it ideal for improving the signal integrity at the receiver. This integrated circuit is part of the ABT family, which is known for its advanced BiCMOS technology, and it is particularly suitable for interfacing with bus lines in a wide range of computing and telecommunications systems.

Key features of the SN74ABT2244ADBRG4 include its two separate enable inputs for each set of four drivers, which allow for greater flexibility in controlling the output states. In the high-impedance state, the outputs neither load nor drive the bus lines significantly, ensuring minimal cross-talk and bus disturbance. With its 3-state outputs, the SN74ABT2244ADBRG4 can also be used in bus-oriented systems where multiple drivers can share the same bus lines.

The device operates over a wide voltage range of 4.5V to 5.5V and features a typical output edge rate of 3.5 ns, which is conducive to improved operating speeds and reduced signal transition times. This makes the SN74ABT2244ADBRG4 an excellent choice for high-speed memory interfacing, bus transceivers, and buffer memory address registers.

The SN74ABT2244ADBRG4 is packaged in a SSOP (Shrink Small Outline Package) DB type with 20 pins, offering a compact footprint for space-constrained applications. The package is also characterized for operation from -40°C to 85°C, providing reliable performance across a wide range of environmental conditions.

With its robust design and advanced technology, the SN74ABT2244ADBRG4 by Texas Instruments stands out as a superior choice for designers looking for a reliable and efficient solution to drive bus lines while maintaining signal integrity in their digital systems.
