Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the TSSOP-16 package and reel packaging configuration. Confirm that the AEC-Q100 qualification status matches your application requirements, as standard commercial grades may differ from automotive variants. Ensure the manufacturer part number aligns exactly with the datasheet specifications before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when multiple independent 2-input data paths are required within a single integrated circuit. The wide voltage range allows compatibility with various logic families. Consider the TSSOP-16 footprint for space-constrained designs requiring surface-mount assembly. Verify thermal performance meets system constraints given the operating temperature range.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHC157 series of quad multiplexers. It shares functional similarities with other members like SN74AHC157N (PDIP) and SN74AHC157DGVR (TVSOP), differing primarily in package type and manufacturing lot characteristics.
