The SN7407DR from Texas Instruments is a hex non-inverting buffer with open-collector outputs. Operating from a 4.75V to 5.25V supply, it provides six independent buffers capable of sinking 40mA. The open-collector design allows for level shifting and wired-OR configurations. It is suitable for driving lamps, relays, or interfacing with higher-voltage systems. Available in a 14-SOIC package.
- High Sink Current (40mA): Directly drives relays, lamps, and LEDs without external transistors.
- Open-Collector Outputs: Enables level shifting to 30V and wired-OR logic connections.
- Simple Non-Inverting Buffer: Easy to use in signal buffering and fan-out applications.
- Industry-Standard 7400 Family: Widely available and well-understood, ensuring design reliability.
Driving High-Voltage Loads
Use the open-collector outputs to drive relays, lamps, or LEDs up to 30V. The SN7407DR can sink up to 40mA per channel, making it ideal for interfacing TTL logic to higher-voltage peripherals.
Level Shifting from 5V to 12V/24V
Connect pull-up resistors to a 12V or 24V supply to shift logic levels. This is common in industrial control systems where 5V logic must drive higher-voltage input modules.
Bus Line Driving with Wire-AND Logic
Implement wired-OR logic by connecting multiple open-collector outputs together. This is useful in interrupt lines or shared bus systems where any device can pull the line low.
Interfacing TTL to CMOS
Use pull-up resistors to 5V or higher to drive CMOS inputs that require higher voltage thresholds. The SN7407DR ensures proper logic levels for mixed-technology systems.
Indicator Lamp Driving in Test Equipment
Drive incandescent lamps or LED arrays directly from logic signals. The 40mA sink capability is sufficient for many indicator applications without additional transistors.
Legacy 5V System Buffering
Buffer signals in older 5V-only systems where the SN7407DR's simple non-inverting function and high current capability are required.
