Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor assets were acquired by ON Semiconductor. Ensure the component designation matches current production status or obsolescence notices from authorized distributors. Confirm package integrity and authenticity through official supply chain channels to avoid counterfeit components. Cross-reference datasheet revisions for any functional updates.

Selection Notes

Select this component for applications requiring 16-bit parallel data storage with tri-state output control in low voltage environments. The bus-hold feature simplifies PCB layout by eliminating external pull-up or pull-down resistors. Consider the 1.1V to 3.6V operating range when designing power supplies. Evaluate EMI requirements, as the internal reduction circuitry offers advantages in noisy electromagnetic environments compared to standard logic families.

Part Context

This part belongs to the 74LCXH series, which represents low voltage CMOS logic devices optimized for high-speed performance and low power consumption. The series is designed to replace higher voltage logic families in modern portable and battery-operated electronics. The 16-bit configuration allows for efficient handling of wide data buses, reducing component count and board space in complex digital systems.

Replacement Considerations

Check for direct equivalents from ON Semiconductor, which now manufactures Fairchild products. Verify pinout and electrical specifications against alternative 16-bit D-type flip-flops with bus-hold features. Ensure voltage tolerance and output drive capabilities match the original design requirements before substitution.
