SN74AHCT244MDWREP

The SN74AHCT244MDWREP is a bidirectional translator for high-performance applications, primarily in high-speed communication, data processing, and remote sensing. It provides logic-level translation from one voltage range to another, allowing data to be transmitted from one logic family to another. This device has an output enable (OE) feature to reduce system power dissipation, as well as a very low quiescent current rating. The SN74AHCT244MDWREP is ideal for use in signal buffering, data transfer, and digital-to-analog signal conversion applications.

Application Field

The SN74AHCT244MDWREP is a versatile buffer used to provide a high-performance, quick and accurate interface to the logic levels of modern digital systems. It enjoys broad acceptance in high speed applications such as sampling valves, counter registers, logic level shifting, data bus transceivers, bus-hold registers and line drivers. Other applications include logic level translation, signal buffering, video output buffering, and signal distinction. It is often used for EDGE and synchronous memory interfacing in military, data processing, and high speed communication applications.

Working Principle

The SN74AHCT244MDWREP is a bus interface logic device that provides low-voltage, low-power logic translation up to 15Mbps. The device acts like a buffer, isolating the input pins from the output pins, providing an electrical buffer between the two power domains. It uses two voltage rails to convert the logical levels between different logic families. When the input logic is high, logic one (VCC) is represented by the bus input, while when the input logic is low, logic zero (GND) is presented. A logic one is transferred to the output pin, while a logic zero is translated to the opposite logic level at the output pin.

The SN74AHCT244MDWREP operates over a wide supply voltage range of 2.0V–5.5V, allowing it to be used in both 3.3V and 5V environments, thus providing a great degree of flexibility for designers. The device provides low power consumption for improved efficiency, as well as high-speed operation. By providing surge suppression, it minimizes the possibility of data-corruption from instantaneous voltage transients. Furthermore, the SN74AHCT244MDWREP boasts a slew rate of 45ns and is optimized for low-cost, low-power applications.

Conclusion

The SN74AHCT244MDWREP from Texas Instruments is a highly reliable, versatile buffer/translator used in signal buffering and data transfer applications. It is well suited to high speed communication and synchronous memory interfacing. The device features a wide supply voltage range, high speed operation, and a low power consumption.
