CD40107 Dual 2-Input NAND Buffer/Driver DIP-8 (CD40107 DIP IC)
The CD40107 is a monolithic CMOS integrated circuit featuring two independent 2-input NAND gates with open-drain output transistors. This configuration allows the IC to serve as a high-current driver capable of sinking up to 136mA, making it suitable for interfacing low-power logic with high-power loads.
This IC is primarily used for driving relays, lamps, LEDs, and MOS gate drivers where high-current sinking is required. It is a popular choice for Arduino electronics projects in India that require a robust interface between microcontroller signal levels and industrial or hobbyist power components.
