Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free composition and RoHS compliance as per Texas Instruments documentation. Confirm the package outline matches the 8-SOIC (0.209 inch) dimensions required for your PCB layout. Ensure the operating environment stays within the specified 0°C to 70°C commercial temperature range. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual differential driver is needed for RS-422 or RS-485 networks. It is appropriate for designs requiring 10 Mbps data rates and standard 5V logic levels. Consider the 8-SOIC package size for space-constrained surface-mount assemblies. Verify that the load capacitance requirements of the bus do not exceed the driver's capabilities at the desired speed.

Drivers, Receivers, Transceivers Part Context

The SN75158DG4 belongs to the SN75158 family of dual differential line drivers from Texas Instruments. It serves as a functional equivalent to older National Semiconductor parts like the DS7830. The 'DG4' suffix specifically denotes the SOIC package variant with lead-free and RoHS-compliant materials, distinguishing it from PDIP or other package options within the same electrical family.

Drivers, Receivers, Transceivers Replacement Considerations

The SN75158D is the non-RoHS equivalent. The SN75ALS191 offers similar functionality but may have different switching characteristics. Verify pinout compatibility before substituting with any alternative dual differential line driver.
