high noise immunity logic gate

The CD4093 DIP Quad 2-Input NAND Schmitt Trigger is a CMOS IC featuring four independent NAND gates with Schmitt trigger inputs, providing hysteresis for stable and reliable logic transitions even with noisy or slow input signals. Operating over a wide voltage range (3V to 18V), the IC is ideal for signal conditioning, level shifting, timing circuits, and digital logic applications. Packaged in a DIP-14 format, it is perfect for breadboard and PCB integration in digital systems.
