Features of 74AC11240DWRG4

The 74AC11240DWRG4 offers several key features and benefits. Some of the principal features include:• Four independent line driver outputs• An active LOW Receiver input• High drive capability• Compatible with TTL logic levels• Low input current• Low quiescent (standby) current• Low power consumption• High speed operation• Improved noise immunity

Working Principle of 74AC11240DWRG4

The working principle of the 74AC11240DWRG4 is based on its ability to convert and increase the drive capability of TTL or CMOS input signals, while operating with a reduced supply voltage. The active-LOW receiver input provides a default logic state of HIGH prior to the arrival of signals, which enables the device to enable output immediately when the device is energized. The output stage of the device is comprised of four independent driver circuitries, each providing a HIGH drive level. The 74AC11240DWRG4 produces a HIGH output when its input is a LOW. The output stage of the device is clamped to a diode drop below the supply voltage, which prevents any destruction of the device due to voltage transients. The device is typically powered from a single +5V supply and consumed very little power, making it ideal for low power applications. The active input stage of the device operates at fast TTL speeds, making it suitable for high-speed applications. The fast switching times of the device reduce crosstalk levels between channels, providing improved EMI/RFI immunity.

Conclusion

The 74AC11240DWRG4 is an advanced CMOS logic buffer and driver device with four independent Line Driver outputs and one receiver input. It is exceptionally fast, has low power consumption, and improved noise immunity compared to conventional bipolar technology. It is widely used in many applications, including digital logic buffers, communication interface circuits, counter drivers, and driver interfacing between digital and analog systems.
