What are the key features of SN7406N-NG?

  • Open-collector outputs rated to 40V enable direct driving of relays, lamps, and indicator LEDs from TTL logic
  • High sink current capability of 40mA per channel allows robust interface with inductive and resistive loads
  • Hex inverter configuration with six independent channels maximizes logic density in through-hole 14-pin DIP designs

What is SN7406N-NG used for?

The SN7406N-NG is widely used to interface TTL logic circuits with high-voltage peripheral loads such as relays, indicator lamps, LEDs, and solenoids in industrial control and automation systems. Its open-collector outputs allow flexible wired-OR connections and voltage level translation up to 40V, making it useful in motor control panels and signal conditioning circuits. The through-hole DIP package suits both production assemblies and field-repair applications in industrial and laboratory environments.

Frequently Asked Questions

What is the output voltage rating of the SN7406N-NG open-collector outputs?

The SN7406N-NG open-collector outputs are rated to withstand up to 40V collector-to-emitter voltage, enabling direct connection to higher-voltage circuits, relay coils, and indicator lights beyond the standard 5V TTL operating range.

What is the maximum sink current per channel of the SN7406N-NG?

Each of the six inverting channels on the SN7406N-NG can sink up to 40mA, providing sufficient drive capability for small relays, indicator LEDs, and optocoupler inputs in industrial control and signal interfacing applications.

What package does the SN7406N-NG use?

The SN7406N-NG is housed in a 14-pin DIP (Dual In-Line Package) for through-hole PCB mounting. This package is easy to handle in prototyping and repair applications, and fits standard IC sockets for field replacement in industrial equipment.

How many channels does the SN7406N-NG have?

The SN7406N-NG contains six independent inverting buffer channels, each with open-collector output. This hex configuration allows a single IC to control up to six separate loads or logic signals simultaneously in compact TTL-based designs.

What are the typical applications for the SN7406N-NG?

Typical applications include relay drivers, lamp drivers, LED indicators, solenoid controllers, and level-shifting from 5V TTL logic to higher-voltage systems. The open-collector outputs support wired-AND logic and direct load switching in industrial automation and embedded control systems.
