Flip Flops Procurement Notes

Verify that the specific part number matches the required package type and manufacturer specifications. Confirm compliance with environmental regulations such as RoHS status if applicable to your project requirements. Ensure that the supplier provides authentic components from authorized channels to guarantee performance reliability and long-term availability for production needs.

Flip Flops Selection Notes

Select this component when a 10-bit unidirectional buffer is required for high-speed applications up to 83.3 MHz. Consider the PDIP-24 package for through-hole mounting needs. Evaluate the 0.064 A drive capability against the load requirements of the destination circuitry to ensure adequate signal integrity and noise margins during operation.

Flip Flops Part Context

This device belongs to the FCT series of fast CMOS logic components designed for high-speed digital applications. It serves as a bridge between different logic levels or buffers complex bus structures. The 10-bit configuration allows for efficient handling of wide data paths, making it suitable for systems requiring parallel data transmission with minimal propagation delay.

Flip Flops Replacement Considerations

Cross-reference with other manufacturers offering equivalent 10-bit bus drivers in DIP-24 packages. Verify pinout compatibility and electrical characteristics such as supply voltage and drive current before substitution.
