The SN7407N is a 6-channel non-inverting buffer from the 7400 TTL family. It operates at 5V (4.75V-5.25V) and features open-collector outputs capable of sinking 40mA. This allows driving high-voltage loads, level shifting, and wired-OR configurations. The 14-DIP package is ideal for through-hole prototyping and legacy systems. Typical applications include relay driving, LED indicators, and industrial control interfaces.
- Open-Collector Outputs: Allows driving loads up to 30V and wired-OR logic connections.
- High Sink Current (40mA): Directly drives relays, lamps, and high-current LEDs.
- Standard TTL Compatibility: Works with existing 5V TTL systems without modification.
- Through-Hole DIP Package: Easy to prototype and integrate into legacy designs.
Driving High-Voltage Loads
The open-collector outputs allow the SN7407N to switch loads up to 30V (with external pull-up), making it suitable for driving relays, lamps, and LEDs.
Level Shifting to Higher Voltages
By using external pull-up resistors, it can translate 5V TTL signals to 12V or 24V logic levels for industrial control systems.
Wired-OR Bus Interfacing
Open-collector outputs enable multiple buffers to be connected together for wired-OR logic, useful in interrupt lines and shared buses.
Driving High-Current Indicators
With 40mA sink capability, it can directly drive high-current LEDs, incandescent lamps, or small relays without additional transistors.
Legacy TTL System Buffering
It provides signal buffering and fan-out expansion for older 5V TTL-based systems, ensuring signal integrity.
Industrial PLC Outputs
It can interface TTL logic with industrial PLC input modules requiring higher voltage or current levels.
