74HC00 - Quad 2-Input NAND Gate IC Arduino UNO It has space for components74HC00 Quad 2 Input NAND Gate IC The 74HC Series 74HC00 IC is a 14 Pin Quad 2 Input NAND Gate IC. This device contains four independent gates each of which performs the logic NAND function. NAND gates utilize advanced silicon gate CMOS technology to achieve operating speeds similar to LS TTL gates with the low power consumption of standard CMOS integrated circuits. All gates have buffered outputs. All devices have high noise immunity and the ability
