Multivibrators Applications

• Timing and pulse-generation circuits
• Debouncing switches
• Pulse-width modulation
• Frequency division

Multivibrators Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's current datasheet to confirm pinout and package dimensions, as variations exist within the 74HC123 family. Confirm RoHS compliance status via official documentation, as manufacturing changes may affect environmental declarations. Ensure the source document explicitly lists CD74HC123NS to avoid confusion with similar packages like N or PW.

Multivibrators Selection Notes

Select this component when dual independent timing channels are required in a single surface-mount package. The HC series offers higher speed than standard 74LS counterparts while maintaining CMOS power efficiency. Verify that the 25 ns propagation delay meets system timing requirements. Ensure the 16-SOIC footprint matches the PCB layout constraints.

Multivibrators Part Context
