The 74HCT03D.652 is a six-input quad 2-input NAND gate IC from Nexperia. It is a low power CMOS device that functions as four independent 2-input NAND gates, designed for high noise immunity and high speed. The device can operate with supply voltages of 2 V to 6 V, with a typical operating supply voltage of 5 V. It has a high fan-out capability, low propagation delay, and can drive up to 16 LSTTL loads. The output is open-drain and can be connected directly to other open-drain outputs in order to wire it into integrated circuits. The IC is suitable for many applications such as subtractors, data selectors, memory element selectors, multiplexers, and more.
