74AUC2G241DCURG4

The 74AUC2G241DCURG4 from Texas Instruments is a low voltage dual logic gate expander. The expander works with a low voltage of 1.8 V for TTL and 0.8 V for CMOS. The device provides eight general purpose buffers with independent control over inversion and access to their output state.

Application Field

The 74AUC2G241DCURG4 is well-suited for interface communication, data transfer and bus decoding applications in generic logic. It is commonly used for different communication protocols such as CAN, Ethernet and RS-485. Other applications include LED control, power supply design and motor control.

Working Principle

The 74AUC2G241DCURG4 is used as an interface logic function between two different logic families. The two inputs (A and B) are connected to the corresponding logic family. When the inputs A and B are different logic families, their states will be transmitted back inverted. The expander can drive the relay circuits, fans, solenoids and lights. It can also measure the input signals which are sent to it and compare them with the values stored in its memory.

The chip does not contain any type of element that can produce heat, making it suitable for high temperature applications. The expander integrated circuits also have better noise margins and output drive capability than regular logic gates. The expander operates within a temperature range of −55°C to 125°C.

Conclusion

The 74AUC2G241DCURG4 is a dual low voltage logic gate expander designed for general purpose applications requiring connectivity between different families of logic. It is commonly used for various communication protocols such as CAN, Ethernet and RS-485. Other applications include LED control, power supply design and motor control. It has improved noise margins and output drive capability compared to regular logic gates and operates within a temperature range of −55°C to 125°C.
