IDT74FCT807BTQ

Clock Buffers, Drivers Overview

The IDT74FCT807BTQ is a high-speed clock driver manufactured by Renesas Electronics, belonging to the 74FCT family. It functions as a 1:10 clock buffer with TTL-compatible outputs, designed for distributing clock signals in digital systems. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum frequency of 100 MHz. It is available in a 20-pin SSOP package and is rated for an operating temperature range of -40°C to +85°C. This component serves as a fan-out buffer to drive multiple loads while maintaining signal integrity.

Clock Buffers, Drivers Feature Summary

• 1:10 Clock Distribution Ratio
• TTL Compatible Outputs
• 100 MHz Maximum Frequency
• 20-SSOP Package

Clock Buffers, Drivers Applications

• Clock distribution networks
• Digital system timing
• Bus-oriented transmitter/receiver applications

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'Q' against official Renesas documentation, as standard listings often use 'BTQG8' or similar variants. Confirm current lifecycle status, as many FCT series parts are discontinued. Ensure compatibility with existing 5V logic levels and check for RoHS compliance details in the latest datasheet before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a single clock source needs to drive ten TTL-compatible loads. Ensure the design requires 5V operation, as the device is not specified for 3.3V logic levels. Verify that the 100 MHz speed meets the system requirements and that the SSOP package fits the PCB layout constraints.

Clock Buffers, Drivers Part Context

This part is part of the broader 74FCT (Fast CMOS TTL) family, which bridges the performance gap between standard CMOS and TTL logic. It offers low power consumption typical of CMOS with the drive strength and input/output compatibility of TTL. The IDT branding indicates its origin from Integrated Device Technology, now part of Renesas.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes include the 74FCT807BTQG8 or 74FCT807BTPYGI8 from Renesas/IDT. Verify pinout compatibility and electrical specifications before substitution. Other manufacturers may offer equivalent 1:10 TTL clock buffers, but ensure voltage and speed ratings match.
