Working Principles

The DG381BDJ is based on CMOS technology, which utilizes both NMOS (N-channel Metal-Oxide-Semiconductor) and PMOS (P-channel Metal-Oxide-Semiconductor) transistors. The NAND gate configuration allows it to perform logical AND operation on the inputs and then invert the output.

When the input signals are at logic high levels, the NMOS transistors conduct, allowing current to flow through them. This pulls the output node to a logic low level. Conversely, when any of the input signals is at logic low, the corresponding NMOS transistor turns off, preventing current flow and allowing the output node to remain at logic high.

Detailed Application Field Plans

The DG381BDJ can be used in various digital systems and applications, including:

1. Microcontrollers and microprocessors
2. Programmable Logic Controllers (PLCs)
