Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the TSSOP-20 surface-mount package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage levels match the selected supply voltage range to prevent undefined states during operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring octal signal inversion with bus isolation capabilities. The HC series offers wide supply voltage flexibility compared to HCT variants. Verify that the TSSOP-20 footprint aligns with existing PCB layout constraints and thermal management requirements for the target application environment.
