The MC14073BCP is a dual 4-input NAND Schmitt trigger from ON Semiconductor. It is a 4-input NAND gate with Schmitt Trigger (inverted) input stages for reduced hysteresis on switching levels, making it suitable for noisy environments. This device features input and output levels of either 5V or 15V for both TTL and CMOS compatibility, is temperature compensated, and features low output impedance. Additionally, it features a high noise immunity rating of 25kV/us and is designed for low voltage logic operations.
