SN74LVC244APWRE4

The SN74LVC244A octal bus buffers are designed for asynchronous communication between data buses. This means that they can be used to connect two data buses that are running at different clock speeds. The buffers will automatically translate the signals between the two buses, ensuring that the data is transmitted correctly.

The SN74LVC244A buffers are also designed to operate with a wide range of supply voltages, from 1.65V to 3.6V. This makes them ideal for use in battery-powered systems and other applications where power consumption is a concern.
