Counter Dividers Procurement Notes

Verify the manufacturer designation as Quality Semiconductor or its authorized successors. Confirm the SOP-16 package variant matches design constraints. Ensure RoHS compliance status aligns with project requirements. Validate that the FCT series specifications meet interface needs. Cross-reference datasheet revisions for any functional updates.

Counter Dividers Selection Notes

Select this component when synchronous 8-bit counting with asynchronous reset is required. Ensure the system operates at 5V nominal supply. Verify that TTL-level compatibility is necessary for interfacing. Consider the SOP-16 footprint for PCB layout. Evaluate speed requirements against FCT series performance characteristics.

Counter Dividers Part Context

This part belongs to the FCT (Fast CMOS) logic family, which bridges the performance gap between standard TTL and advanced CMOS technologies. It provides higher switching speeds than bipolar devices with significantly lower power dissipation. The family is designed for high-density digital systems requiring reliable data handling and fast propagation delays.

Counter Dividers Replacement Considerations

Check for direct pin-compatible alternatives within the same FCT series. Verify electrical parameters such as propagation delay and drive current match original specifications. Ensure package dimensions remain identical for board replacement. Confirm logical function equivalence before substitution.
