Procurement Notes
Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor. Confirm that the NOPB suffix indicates lead-free and RoHS compliance status according to current datasheets. Check availability status as older National Semiconductor part numbers may have specific lifecycle constraints or obsolescence notices.
Selection Notes
Select this component when a quad receiver configuration is required for RS-422 applications. Ensure the design accommodates the 5V supply voltage requirement. Verify that the SOIC-16 package footprint matches the PCB layout. Consider thermal dissipation requirements if multiple units are placed closely together on the board.
Part Context
This part belongs to the DS26LS32 family of quad differential line receivers. It serves as the receiving counterpart to drivers like the DS26LS32. The device is widely used in legacy and industrial interfaces where reliable long-distance transmission over twisted pair cables is necessary.
