Procurement Notes

Verify the specific suffix YZPR corresponds to the DSBGA-8 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the ordering part number matches the exact functional specification for the retriggerable monostable multivibrator variant.

Selection Notes

Select this component when a single-channel retriggerable timer is required in a compact surface-mount footprint. The LVC series offers compatibility with modern low-voltage logic systems while maintaining robust drive capabilities. Consider the 18.6 ns propagation delay and 32 mA output strength for driving moderate loads in space-constrained designs.
