7406 Hex Inverter IC – High-Voltage Open-Collector DIP-14 Logic Chip

Overview 

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.

Key Features 

• 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.

Technical Specifications 

Ideal Applications 

• Relay & Solenoid Drivers: Driving electromechanical components directly from digital logic lines.

• Lamp & LED Driving: Controlling higher-voltage indicator bulbs or LED matrices.

• Level Shifting: Translating 5V logic signals up to higher voltage domains.

• Industrial Automation: Interfacing legacy digital control boards with external electromechanical hardware.
