DS34C87TMX/NOPB

Overview

The DS34C87TMX/NOPB is a CMOS quad differential line driver manufactured by Texas Instruments, designed for RS-422 communication interfaces. It operates within a supply voltage range of 4.5 V to 5.5 V, with a typical operating voltage of 5 V. The device supports data transmission rates up to 30 Mb/s and features four independent drivers without integrated receivers. It draws a maximum operating supply current of 500 uA. The component is housed in a 16-pin SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Quad differential line driver configuration supporting RS-422 standards
• High-speed data transmission capability up to 30 Mb/s
• CMOS technology ensuring low power consumption
• Tri-state outputs for bus line isolation

Applications

• RS-422 serial communication systems
• Industrial control network interfaces
• Data acquisition system transceivers
• Multi-drop communication lines

Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free compliance and specific packaging options such as reel or cut tape. Confirm the manufacturer source is Texas Instruments directly or authorized distributors to ensure authenticity. Check RoHS status details on official datasheets prior to final procurement decisions.

Selection Notes

Select this component when a 5 V supply is available and RS-422 compatibility is required. Compare against the DS34LV87TMX/NOPB if lower voltage operation at 3.3 V is necessary. Ensure the application requires only transmitter functionality, as this device lacks integrated receivers. Verify thermal requirements align with the specified -40°C to +85°C operating range.

Part Context

This device belongs to the DS34C87T series of interface integrated circuits. It serves as a dedicated driver solution within Texas Instruments' portfolio of RS-422 components. The part is distinct from transceiver models by providing only output driving capabilities for differential signaling applications.

Replacement Considerations

DS34LV87TMX/NOPB offers similar functionality but operates at 3.3 V instead of 5 V.
