Counter Dividers Procurement Notes

Verify the specific EG4 suffix indicates the lead-free RoHS-compliant variant with the exposed thermal pad on the TSSOP-16 package. Confirm that the manufacturer datasheet explicitly defines the electrical characteristics for this exact suffix, as packaging and thermal properties may differ from standard versions. Ensure compatibility with assembly processes requiring thermal dissipation through the bottom pad.

Counter Dividers Selection Notes

Select this component when an 8-bit synchronous down counter is required with wide voltage flexibility. The HC series offers high noise immunity suitable for general-purpose digital logic. Consider the TSSOP package with thermal pad if board space is limited but heat dissipation is necessary. Verify that the positive edge trigger aligns with the system clock polarity requirements.
