Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix '652' against official NXP documentation to confirm package variant and tape-and-reel specifications. Ensure the sourcing channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with the distributor's catalog to prevent substitution errors with non-HCT variants or different pin configurations.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 4-to-16 decoding function is required with TTL-compatible input thresholds. The HCT series ensures noise immunity and low power consumption compared to older LS logic families. Consider the SOP-16 footprint constraints and the necessity for inverted outputs before finalizing the design integration.
