IDT74FCT3807Q8

The IDT74FCT3807Q8 is part of the IDT FCT family of clock and timing devices, and is a low-skew 3-state 1-to-8 non-inverting buffer. It is designed to minimize propagation delay times and reduce the system’s clock routing requirements. It can provide fan-out of two or more clocks. It is suitable for high performance systems and can be used in clock and data distribution networks or in memory systems.

The IDT74FCT3807Q8 can be used as a 1-to-8 buffer, 1-to-4 buffer/driver, or a 1-to-2 buffer. The ‘Q8’ part of its name suggests that it has eight outputs. It has an input pin (A1), eight output pins (Q0 through Q7), and eight output enable pins (OE0 through OE7). It is designed for low-skew, high-speed and low-power applications, making it suitable for a variety of applications in a variety of industries.

Working Principle

The IDT74FCT3807Q8 works by connecting an input signal to the input pin (A1) and then applying the appropriate level (low or high) to the output enable pins. Each output enable pin corresponds to one of the output pins. When the level applied to the output enable is a logical 1, then the signal at the output pin will be the same as the input signal. When the level applied to the output enable is a logical 0, then the output will be in a high-impedance state. This allows multiple outputs to be connected together without them interfering with each other.

Application Field

The IDT74FCT3807Q8 is designed for a wide range of applications. It is ideal for high speed clock distribution, memory system designs and applications requiring multiple clocks in close proximity. It can be used in consumer electronics, military/aerospace, automotive, industrial, communications and computer systems.

In consumer electronics, it can be used for data bus applications and clock distribution for high-speed applications. It is suitable for low-skew applications in memory systems, such as synchronous DRAMs, SRAMs and FIFOs. In automotive, it is suitable for bus transceivers, signal and timing signal distribution, and embedded controllers.

In industrial applications, the IDT74FCT3807Q8 can be used for signal and timing signal distribution in large system designs, such as static RAMs, dynamic RAMs, serial peripheral interfaces and microprocessors. In communications and computer systems, it can be used for backplane applications, clock distribution, signal routing and interconnects.
