Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75189ADRG4 is determined by strict equivalence across the following critical parameters:

• Protocol specification: RS232
• Receiver/driver configuration: 0 drivers, 4 receivers
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: 0°C ~ 70°C
• Package type: 14-SOIC surface mount
• Base product number: SN75189

The SN75189ADR meets all substitution criteria as a direct functional equivalent, differing only in packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The SN75189ADR is the direct substitute for the SN75189ADRG4. Both components share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: the SN75189ADRG4 is discontinued, while the SN75189ADR maintains active status with higher inventory availability. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Selection of the SN75189ADR ensures continued access to functionally equivalent RS232 receiver capability with confirmed supply chain availability.
