Texas Instruments 20-SOIC SN74ALS540DWR

The SN74ALS540DWR is a quadruple 2-input OR gate IC from Texas Instruments, belonging to the Advanced Schottky Logic (ALS) family. It features four independent channels that each perform an OR logic function on two inputs, delivering high-speed performance and low power consumption compared to standard TTL. Packaged in a DWR (Dual-Width Rohs-compliant Tape and Reel) form factor for automated SMT assembly, it's suitable for high-volume production and commonly used in digital circuit designs where multiple signal routing or combining is required.
