The 74HCT00 is a Quad 2-input NAND Gate IC comprised of four individual NAND gates, each with two inputs. The 74HCT00 is a CMOS device and is typically packaged in a 14-pin DIP. It operates over a wide voltage range, typically 2 to 6 V. It has fast switching speeds, high noise immunity, and low power consumption making it suitable for a variety of applications such as logic-level conversion, multiplexers, decoders, analog switches, and processors. This device is manufactured by Motorola and is part of their 74HCT series.
