The CY74FCT244ATQCTG4 is a Low Skew Octal Buffer/Driver with 25 Ohm series resistors in the outputs designed to improve drive characteristics. Therefore, output drive capability and balanced line reflections of the device are secured, avoiding transmission line effects and allowing for more reliable communications. The device is useful for high speed data distribution applications such as clock distribution and bus repeater functions.

As a logic device, the CY74FCT244ATQCTG4 belongs to the category of "Buffers, Drivers, Receivers, Transceivers". Buffers are devices for providing an impedance match between two points in a circuit, drivers are devices for supplying the optimal driving voltage and current to the output of a circuit, receivers are devices that accept signals from drivers and convert them into usable square wave logic signals, and transceivers are devices that can multiplex, or combine, two or more different signals or pieces of data onto a single signal or communication channel.

The CY74FCT244ATQCTG4 device enables multiple signal line uses, as it offers a programmable forcing function with a parallel enable signal. This offers some flexibility, as the device may support both 8bit and 16bit data multiplexing through the E0 and E3 pins. It also supports signal integrity between sender and receiver, by use of the 25 Ohm series resistors in the outputs, allows for improved drive characteristics over standard logic devices which have 50 Ohm series resistors.

The internal signals from driver and receiver sections are protected from bus contention, which may otherwise cause erroneous operation, by use of logic circuitry that detects conditions from the voltage levels at the outputs. Also, tri-state buffers, located in the receiver and driver sections, offer support to high-speed switching problems.

The CY74FCT244ATQCTG4 device has multiple operating modes, as it is able to operate on power supplies ranging from 3.3v to 5v. This allows flexibility and cost savings, as the same device can be used in both 5v and 3.3v application designs. Operating at either voltage level, the device ensures a high voltage of up to 5v. It has an operating frequency of up to 150Mhz at 5v, and up to 100Mhz at 3.3v, making it suitable for low to medium speed applications.

The CY74FCT244ATQCTG4 device may be applied in multiple application fields, being useful for a wide range of purposes. It can be used for data transmission, clock distribution, bus repeater, multiplex signal line and mixed voltage networking, as well as in hot plugging and signal fanout applications.

In conclusion, the CY74FCT244ATQCTG4 device is a reliable, low-skew octal buffer/driver with 25 Ohm series resistors in the outputs, designed to improve drive characteristics. It offers multiple modes of operation, from 3.3v to 5v and from low to medium speed of up to 150Mhz/100Mhz respectively. It is a logic device belonging to the "Buffers, Drivers, Receivers, Transceivers" category and can be applied in multiple application fields, such as data transmission, clock distribution, bus repeater, multiplex signal line and mixed voltage networking, as well as hot plugging and signal fanout applications.
