The SN7406D is an IC (integrated circuit) component manufactured by Texas Instruments. It is a hex inverter with open-drain outputs, belonging to the 7400 series logic family. The SN7406D is designed for general-purpose digital applications and can be used in a wide range of electronic circuits.
One of the key features of the SN7406D is its hex inverter functionality. It consists of six separate inverter gates, each capable of converting the input signal to its complementary output. The open-drain outputs are particularly useful for applications that require wired-OR connections or active-low outputs.
Another important feature of the SN7406D is its wide operating voltage range. It can operate from 4.75 volts to 5.25 volts, making it compatible with both standard TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) voltage levels. This flexibility allows for seamless integration with various types of digital logic circuits.
In terms of electrical characteristics, the SN7406D has a maximum propagation delay of 12 nanoseconds, ensuring fast signal processing. It has a fan-out of 10 TTL loads, meaning it can drive up to ten standard TTL inputs without the need for additional buffering. This feature makes it an efficient and reliable component in many digital systems.
Furthermore, the SN7406D offers a high noise immunity due to its Schmitt-trigger inputs
