SN75189ADRG4

Drivers, Receivers, Transceivers Overview

The SN75189ADRG4 is a quadruple line receiver manufactured by Texas Instruments, designed for RS-232 interface applications. It operates with a single 5 V power supply and supports data rates up to 1 Mb/s. The device features four independent receivers in a 14-pin SOIC package (SOIC-14). It functions within an operating temperature range of 0°C to +70°C and draws a typical supply current of 26 mA. The component lacks ESD protection and does not include a shutdown feature. It is supplied in reel packaging.

Drivers, Receivers, Transceivers Feature Summary

• Provides four independent line receivers for converting RS-232 signals to TTL-compatible logic levels.
• Operates reliably on a standard 5 V single power supply without requiring negative voltage rails.
• Supports data transmission speeds up to 1 Mb/s for serial communication interfaces.

Drivers, Receivers, Transceivers Applications

• RS-232 serial communication systems
• Industrial control equipment interfaces
• Modem signal reception circuits

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the package type is SOIC-14 and the operating temperature grade is commercial (0°C to +70°C). Ensure the reel quantity matches project requirements, typically 2,500 units per manufacturer standard packaging for this variant.

Drivers, Receivers, Transceivers Selection Notes

Select the SN75189ADRG4 when only signal reception from RS-232 lines is required, as it contains no drivers. Compare against the SN75188ADR if transmission capability is needed instead. Verify that the 14-pin SOIC footprint fits the PCB layout constraints. Check if ESD protection is necessary for the application environment, as this device lacks built-in ESD safeguards.

Drivers, Receivers, Transceivers Part Context

This component belongs to the SN75189A family of quadruple line receivers. It is functionally compatible with the MC1489 and SN55189A specifications. The 'DRG4' suffix denotes the tape-and-reel packaging format and lead-free construction within the SOIC-14 package family offered by Texas Instruments.

Drivers, Receivers, Transceivers Replacement Considerations

SN75189ADR is the non-green equivalent in identical SOIC-14 packaging. SN75C189ADR is a recommended modern replacement offering improved performance characteristics while maintaining pin compatibility.
