SN75157DE4

Drivers, Receivers, Transceivers Overview

The SN75157DE4 is a dual differential line receiver manufactured by Texas Instruments, designed for RS-422 communication interfaces. It operates within a supply voltage range of 4.75 V to 5.25 V, with a typical operating voltage of 5 V. The device supports data rates up to 4 Mb/s and draws a maximum operating supply current of 50 mA. It features two receivers housed in an SOIC-8 surface-mount package. The component functions reliably across an ambient temperature range from 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Dual differential line receiver architecture supporting RS-422 standards
• Surface-mount SOIC-8 packaging for compact circuit integration
• Operational capability at data rates up to 4 Mb/s

Drivers, Receivers, Transceivers Applications

• RS-422 balanced transmission line receiving circuits
• Industrial communication interface modules
• Data acquisition systems requiring differential signal reception

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific DE4 suffix against the manufacturer's official documentation to confirm pinout compatibility and RoHS status. Confirm end-of-life or obsolescence status prior to procurement, as discontinuance notifications may affect long-term availability. Ensure the SOIC-8 package dimensions match the target PCB footprint requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual receiver solution is required for RS-422 applications within a standard 5 V logic environment. Consider the SOIC-8 package constraints for board space. Evaluate the 4 Mb/s speed limit against system requirements. Verify thermal management needs for the 0°C to +70°C commercial temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75157 series of RS-422 interface integrated circuits. The DE4 designation indicates a specific tape-and-reel or tube packaging variant with lead-free composition. It serves as a complementary receiver component to drivers like the SN75158, forming complete transceiver pairs for half-duplex or full-duplex communication links.

Drivers, Receivers, Transceivers Replacement Considerations

The SN75157DR is a direct functional equivalent in the same SOIC-8 package. Other variants within the SN75157 family may offer different packaging or temperature ranges but maintain electrical compatibility.
