Overview
The DS34C87TM/NOPB is a CMOS quad tri-state differential line driver from Texas Instruments, designed for RS-422 interface applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports data rates up to 30 Mb/s. The device features four drivers with no integrated receivers, housed in a 16-pin SOIC package. It draws a typical operating supply current of 500 µA and functions reliably across an industrial temperature range of -40°C to +85°C.
Feature Summary
- Provides four independent differential line drivers for RS-422 communication
- Supports high-speed data transmission up to 30 Mb/s
- Includes tri-state output capability for bus sharing
Applications
- RS-422 serial communication systems
- Industrial control networks requiring differential signaling
- Data acquisition systems with long-distance transmission needs
Procurement Notes
Verify the complete part number including the NOPB suffix to ensure RoHS compliance and lead-free status. Confirm the SOIC-16 package variant matches your PCB footprint requirements. Check the datasheet revision date to ensure compatibility with current design specifications and environmental regulations.
Selection Notes
Select this component when a 5V supply is available and RS-422 differential driving is required. Compare against the DS34LV87TM/NOPB if lower power consumption at 3.3V operation is necessary. Ensure the 30 Mb/s speed rating meets the system's bandwidth requirements without needing higher-performance alternatives.
Part Context
This device belongs to the DS34C87T series of RS-422 interface integrated circuits manufactured by Texas Instruments. It serves as a standard solution for converting single-ended logic signals into balanced differential outputs suitable for noisy environments or longer cable runs in industrial settings.
Replacement Considerations
The DS34LV87TM/NOPB is a direct functional substitute but operates at 3.3V instead of 5V. Verify voltage level compatibility before substitution. Other generic RS-422 drivers may require circuit redesign due to differing pinouts or electrical characteristics.
