The 7406 contains six independent inverter gates featuring high-voltage open-collector outputs. Unlike standard logic gates that output standard 5V digital levels, the open-collector outputs of the 7406 can handle external voltages up to 30V and sink higher currents, making it an ideal bridge between low-voltage microcontrollers or TTL logic and heavy-duty output peripherals.
High-Voltage Outputs: Open-collector driver outputs support up to 30V, allowing direct control of relays, lamps, and discrete displays.
Hex Architecture: Includes six independent inverter channels in a single 14-pin DIP package.
High Current Sinking: Designed to sink substantial output currents compared to standard inverter chips.
TTL Compatible Inputs: Easily interfaces with standard 5V TTL and CMOS logic families.
