The MC14012B B-Suffix Series CMOS Gates is a product produced by Semiconductor Components Industries, LLC. Its main features are low power consumption and high noise immunity. The supply voltage range is 3.0 Vdc to 18 Vdc. All outputs are buffered. It can drive two low-power TTL loads or one low-power Schottky TTL load over the rated temperature range. The working temperature range is -55 to +125°C.
The MC14012B is a dual 4‑input NAND gate from ON Semiconductor’s B‑Series CMOS family. It combines P‑channel and N‑channel MOS devices in a single monolithic structure, offering low power dissipation and high noise immunity. The device features buffered outputs, double‑diode input protection, and is available in Pb‑free packages.
The data sheet provides detailed electrical characteristics, switching performance, package dimensions, and ordering information for PDIP‑14, SOIC‑14 and other package variants. It also includes typical noise‑margin data and guidelines for unused inputs and outputs.
