Texas Instruments 20-SOIC SN74LS244DWG4

The SN74LS244DWG4 is a Texas Instruments-manufactured octal buffer/line driver featuring three-state outputs. It's part of the 74LS logic family and designed to provide bidirectional data transmission in digital circuits. The device contains eight independent buffers with enable inputs (G1 to G4) that control the output states, allowing for high-impedance (Hi-Z) when disabled. Ideal for bus-oriented systems, it operates at standard 5V TTL levels and comes in a 20-SOIC package. With its ability to isolate and drive signals, it's commonly used for interfacing between different logic levels or for driving long signal lines.
