Working Principles

The 74LVC38ABQ,115 is a CMOS-based logic gate that performs the NAND function. It operates on low-voltage supply ranging from 1.65V to 5.5V, making it compatible with both 3.3V and 5V systems. The gate consists of four independent 2-input NAND gates, each with Schmitt-trigger inputs for improved noise rejection.

When both inputs of a NAND gate are high (logic level 1), the output becomes low (logic level 0). In all other input combinations, the output remains high. This behavior allows the gate to perform logical AND followed by logical NOT operations.
