onsemi 20-SOIC 74ACTQ245SC

The 74ACTQ245SC is a high-speed CMOS-based octal bus transceiver from the 74ACTQ series by Fairchild Semiconductor (now part of ON Semiconductor). It functions as a non-inverting tri-state buffer, enabling bidirectional data transfer on an 8-bit bus. The device supports individual output enable control for each direction and features low power consumption with fast switching speeds. Suited for applications requiring low noise and power efficiency in digital systems, it's typically used for bus interfacing or level shifting in circuits where controlled signal transmission is essential.
