Texas Instruments 20-SOIC SN74LS240DWG4

The SN74LS240DWG4 is a quad buffer/line driver IC from Texas Instruments (TI) with three-state outputs, belonging to the 74LS logic family. It's designed for use in digital systems where high fanout capability and control over output states are required. This device has eight channels, each featuring enable inputs that allow the outputs to be placed in a high-impedance state when not driving loads. The 'DWG4' suffix typically denotes a specific package type or manufacturer's code; however, exact details should be confirmed via its most recent datasheet.
