Texas Instruments 20-SOIC SN74AHC240DW

The SN74AHC240DW is a member of the Texas Instruments' 74AHC series, which provides octal (8-channel) open-drain buffers with three-state outputs. These devices are designed for low voltage and high-speed operation, supporting CMOS logic levels while providing high noise immunity and low power consumption. The 'DW package refers to a small-outline dual in-line package (SOIC), suitable for surface mount technology (SMT). It's typically used for bus interfacing or as a general-purpose buffer where multiple signal lines need to be independently controlled or isolated, with the ability to tri-state the outputs for high impedance when not driving a load.
