The 74FCT807CTSOG is a very useful and versatile device that covers many application fields and can be used in various situations. In this article, we’ll be discussing the application fields and working principles of the 74FCT807CTSOG. The Device is a high-speed 3-state octal buffer/line driver designed to be used in clock and timing circuits.

Application Fields

The 74FCT807CTSOG is used to buffer and drive the clocks for high-frequency logic operations, such as the input and output of an FPGA or CPLD. It is designed to interface with both slow and fast logic families. Such applications involve controlling data flow in multi-function systems, synchronization of digital audio/video signals, and driving large data buses between components.

The device can also be used to drive address/control lines within a system, as well as to fan-out data, address and control signals, to multiple devices. The device is also suitable for fan-in applications, where the device can be used to sequentially latch data, address and control signals, from multiple devices.

Working Principle

The 74FCT807CTSOG is a member of the 74FCT family of Octal Clock/Timing Buffers and Drivers. The device operates from a single power supply between 2.5V and 3.6V. It supports three-state output operation which is enabled/disabled via a Control Input pin. For data transfer, the device can operate at speeds up to 275MHz. The device has dynamic noise cancellation circuitry, which helps reduce noise induced by clock cycles.

The device is especially suited for the multiplexing of signals at the input end of FPGAs, CPLDs and other high-speed logic devices. This makes the device particularly suitable for clocks, PAR initiatives, and timing applications. The device supports true and complementary clocks as well as maintaining any frequency that has drops as low as one clock cycle every thousand years.

The device also features an active release structure, which helps minimize power dissipation during hold and idle periods. This feature helps reduce the risk of electrostatic discharge (ESD) damage. The device is also build with advanced static protective circuits to prevent unintentional current flow during static discharging. The device has built-in low I/O capacitance which helps reduce the device power consumption during operation.
