IDT74FCT3807EQI is a high-speed TRI-STATE bus driver that belongs to the Clock/Timing - Clock Buffers, Drivers family. It provides the proper current and voltage levels to the data (D) and enable (E) inputs of various interfacing devices. It also incorporates TRI-STATE enable and disable control for providing an effective data transfer without wasting the energy.

IDT74FCT3807EQI is widely used in high-speed applications ranging from low-power switching applications, microprocessor and microcontroller interfaces, and development and debugging of microcomputers to testing and qualification of ISPs (Integrated Signal Processors). It is also used as a clock driver in high-speed communications systems and ICs, as well as in applications such as digital signal processing and clock and timing systems.

IDT74FCT3807EQI Applications:

• Digital signal processing
• Clock and timing systems
• Low-power switching applications
• Computer buses and networks
• Graphics processors
• High-speed communication systems
• Development and debugging of microcomputers

The IDT74FCT3807EQI operates in either the enable or disable mode, depending on the enable (E) input. When the enable input is high the device can sink or source current up to 100 mA with a 0.4 Vdc (typ) forward diode drop from the drains of its drivers. In the enable mode, the output drivers are capable of driving high logic levels in unison to minimize noise on the bus.

In the disabled mode, the IDT74FCT3807EQI will sink or source no more than 2 µA of current allowing receivers to remain undisturbed if data is not present. When enabled, the device can easily drive up to eight loads and can be configured in four modes depending on the state of the enable pin.

The IDT74FCT3807EQI has two separate power supply inputs: one for VDD and one for VDDQ. The VDDQ pin supplies current to the outputs when the enable pin is in a high state. When the enable pin goes low, current is supplied by the VDD pin. This allows the outputs to remain active even if the enable pin is low. This ensures that data is maintained on the outputs and receivers do not experience glitches.

The IDT74FCT3807EQI also includes an internal self-powered 4-phase clock generator, called an LC loc */which ensures that the outputs have a very low rise and fall time, ensuring maximum system performance. The length of each cycle of the generated clock is configurable, so that the generated clock can be tailored to suit a variety of applications.

Overall, the IDT74FCT3807EQI is an excellent interface solution for high-speed applications. The combination of its low power consumption, low forward diode drop, high drive capability, low-noise design and programmable phase length make it an ideal choice for a wide range of applications.
