The SN7407NSR is a hex non-inverting buffer from Texas Instruments, part of the 7400 TTL logic family. It features six channels of signal buffering with open-collector outputs, allowing for wired-OR connections and level shifting. Operating from 4.75V to 5.25V, it is designed for standard 5V TTL systems. With a 40mA sink capability, it can drive LEDs, relays, and other loads. The 14-SOIC package provides a compact surface-mount solution.
- Open-Collector Outputs: Enables wired-OR logic and level shifting to higher voltages.
- High Sink Current (40mA): Drives LEDs, relays, and other loads directly.
- Six Channels: Provides multiple buffered outputs in a single package.
- Compact 14-SOIC Package: Saves board space in surface-mount designs.
Driving LEDs and Lamps
Use the SN7407NSR to drive LEDs or incandescent lamps directly. The open-collector output can sink up to 40mA, sufficient for many indicator applications.
Level Shifting to Higher Voltages
With open-collector outputs and external pull-up resistors, it can shift 5V logic to 12V or 24V levels for industrial loads.
Wired-OR Logic Implementation
Connect multiple open-collector outputs together to implement wired-OR logic, reducing component count.
Relay and Solenoid Driving
Drive relays or solenoids with external flyback diodes, using the 40mA sink capability to switch inductive loads.
Interfacing with High-Voltage Peripherals
Interface 5V logic with high-voltage peripherals such as vacuum fluorescent displays or power transistors.
Bus Signal Buffering
Buffer signals on a bus with open-collector outputs, allowing multiple devices to drive the line without contention.
