Product Description

The SN74ACT244PWRG4 is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements. This device can be used as two 4-bit buffers or one 8-bit buffer. It features inputs and outputs on opposite sides of the package to facilitate board layout.

The octal buffer/line driver's 3-state outputs are controlled by output-enable (OE) inputs which, when high, place the outputs in the high-impedance state. This is useful for sharing bus lines in a system or for reducing power consumption by placing unused outputs in the high-impedance mode.

With its robust design, the SN74ACT244PWRG4 ensures signal integrity and reduces crosstalk, making it an excellent choice for use in high-frequency data paths. Its TSSOP package ensures a compact footprint on the PCB, saving valuable board space in dense applications.

Applications

Due to its high drive and low power consumption, the SN74ACT244PWRG4 is commonly used in:

• Data communication systems
• Address and data bus buffering
• Memory and microprocessor bus driving
• Signal buffering in telecommunications
