The Texas Instruments SN7407 series consists of hex buffers and drivers featuring high-voltage open-collector outputs for interfacing with high-level circuits (such as MOS) or for driving high-current loads (such as lamps or relays), and also is characterized by its ability to drive 15 LSTTL loads. The SN7407 device is a versatile component that is widely used in digital systems for signal buffering and voltage level shifting.
Key Features
- High-Voltage Outputs: The SN7407 offers high-voltage outputs of up to 30V, providing the ability to directly drive heavier loads than standard digital ICs.
- Open-Collector Outputs: Its open-collector configuration allows multiple outputs to be connected together for increased drive capability or for wired-OR logic functions.
- High-Current Drive: Each output can deliver a high current of up to 40 mA, making the SN7407 suitable for driving a variety of output devices.
- Compatibility: The device is designed to be compatible with standard TTL integrated circuits.
- Multiple Package Options: Available in a variety of packages including PDIP, GDIP, PDSO, and SOIC, providing flexibility for different types of circuit board layouts.
Applications
The SN7407 is commonly used in applications that require a buffer or driver to interface different logic levels or to drive external loads. Its applications include:
- Driving lamps, relays, printer hammers, and other high-current or high-voltage loads in industrial controls.
- Logic level conversion for interfacing between different voltage levels within a digital system.
- Wired-OR logic configurations in digital circuits.
