7406 Hex Inverter Buzzer IC (DIP)

The 7406 Hex Inverter Buzzer IC (DIP) is a versatile and reliable TTL logic device that contains six independent NOT gates (inverters) with open-collector high-voltage outputs. It is designed to invert digital logic signals and can drive higher current loads such as buzzers, relays, LEDs, and lamps directly using external pull-up resistors.

As part of the 7400 TTL logic series, the 7406 is built for compatibility with 5V digital logic systems and can handle output voltages up to 30V, making it ideal for signal amplification and interfacing applications. The IC comes in a DIP-14 (Dual Inline Package), making it easy to mount on breadboards, PCBs, or IC sockets, and is commonly used in educational electronics, embedded systems, and control circuits.

Features:

• Contains six independent NOT (inverter) gates in a single package.
