The CY74FCT827ATQCT is an 8-bit bus-oriented transceiver device with 3-State outputs. It is similar to CY74FCT245ATQCT but with faster propagation delay times and wider output voltage swing. This device is designed as a single-chip solution when multiple bus bus transceivers are required. It has two sets of 8-bit Buffers that allow a fully-bidirectional asynchronous data transfer between two different buses.

The CY74FCT827ATQCT can be used in a wide range of applications. It is commonly used in systems requiring the movement of large amounts of data. For example, it can be used in memory expansion and communication interface applications. It can also be used in bus-oriented applications, such as systems containing multiple processors or data busses.

The CY74FCT827ATQCT also has a special feature called “bus-hold”, which is a built-in capability providing data retention when it is not driven by either bus. This feature works by actively holding the inputs when enabled or when no bus activity is happening. This feature eliminates the need for external bus-hold capacitors or resistors.

The CY74FCT827ATQCT has two independent sets of logic buffers, a receiver and a driver. The receiver buffers take the data present on one bus and output it onto the other. The driver buffers take the data present on the first bus, buffer it, and drives it onto the second bus. Each of these buffers can be inverted individually, allowing either a polarity inversion or an active-low signal. The device can also be operated in three-state mode, in which case the output is disabled.

The CY74FCT827ATQCT has the capability to pass signals that are of different logic standards between two buses simultaneously. This allows it to interface with many logic families, such as TTL, CMOS, and ECL. It is also capable of tolerating a wide voltage range, up to 20 volts. This feature allows the CY74FCT827ATQCT to be used in many different applications, from low-voltage hand-held devices to high-voltage industrial equipment.

The CY74FCT827ATQCT is packaged in both SOIC and TSOP packaging. This allows for easy implementation in both through-hole and surface mount applications. It is also available in a variety of speeds, from 4ns to 18ns, allowing for even more flexibility in terms of system design.

In conclusion, the CY74FCT827ATQCT is a high performance, low power transceiver device suitable for a wide range of applications. It has a wide operating voltage range and is capable of interfacing with multiple logic families. Its built-in “bus-hold” feature eliminates the need for external capacitors or resistors. Finally, it is available in two package sizes, allowing for easy implementation in both through-hole and surface mount designs. The CY74FCT827ATQCT is a great choice for systems requiring multiple bus transceivers and/or a real-time data transfer between two different buses.
