IC-7400 (4 x NAND)

This industry-standard IC (IC 7400) may be controlled by means of 12 4-mm jacks. Integrated Schmitt trigger circuits allow for a variety of digital and analogue signal sources
to be directly connected to it (ON-OFF or Reed switch, NTC, PTC, LDR etc.).
This module is designed to demonstrate the relationship between simple logic gates and industrial applications of integrated circuits.
