About this product
The 7420 is a 74-series TTL logic IC containing two independent 4-input NAND gates. Its output goes low only when all four inputs of a gate are high, which makes it useful for basic digital logic and learning projects. It runs from a 5 V supply and is commonly used on breadboards in digital electronics courses.
