Texas Instruments 20-SOIC SN74ALS520DWRE4

The SN74ALS520DWRE4 is a quad 2-input positive-NAND gate logic integrated circuit (IC) from Texas Instruments. It belongs to the Advanced Schottky Logic (ALS) family and comes in a 16-pin SOIC (DW) package. This device operates with a supply voltage range typically from 4.75V to 5.25V, providing high-speed performance with low power consumption. Each gate functions at speeds up to 100 MHz and has standard CMOS input thresholds for compatibility with TTL circuits. The part is suitable for general-purpose logic applications where multiple NAND gates are required in compact designs.
