onsemi 20-SOIC DM74AS244WM

The DM74AS244WM is a quad tri-state buffer/line driver/line receiver integrated circuit from the 7400 series. It features individual output enable lines for each of its four channels, allowing it to act as a bus transceiver with high-impedance states. This device is suitable for digital systems where data needs to be transferred across a shared bus without interfering with other devices on the same bus. The part is available in a surface-mount package and typically operates with standard TTL voltage levels.
