Overview
The DS34C87TN/NOPB is a CMOS quad tri-state differential line driver designed for digital data transmission over balanced lines. It meets EIA standard RS-422 requirements while maintaining low power consumption. The device accepts TTL or CMOS input levels and translates them to RS-422 output levels. It operates from a single 5V supply with a voltage range of 4.50V to 5.50V. Typical propagation delays are 6 ns, and typical output skew is 0.5 ns. Quiescent supply current is typically 500 μA at VCC = 5V. The component is available in SOIC-16 packages.
Feature Summary
- TTL and CMOS input compatibility
- Outputs do not load the line when VCC is 0V
- Tri-state outputs for system bus connection
- Separate enable circuitry for each driver pair
Applications
- Serial communication interfaces
- Terminal interfaces
- Balanced line digital data transmission
Procurement Notes
Verify the exact package type against the datasheet, as the 'N' suffix typically indicates a PDIP package, but the provided source material only lists SOIC variants (DS34C87TM/NOPB) as active. Confirm availability status directly with Texas Instruments or authorized distributors, as the specific part number may be discontinued or require verification of the correct suffix for the desired form factor.
Selection Notes
Select this component for applications requiring RS-422 compliant differential signaling with low power consumption. Ensure the design accommodates the 5V operating voltage and utilizes the separate enable pins for proper bus management. Verify that the chosen package variant matches the PCB layout requirements, noting that the provided documentation primarily details SOIC packaging options.
Part Context
The DS34C87T belongs to the family of CMOS quad differential line drivers from Texas Instruments. It is pin-compatible with the DS3487T. The device is designed to provide robust signal transmission over balanced lines while minimizing power usage, making it suitable for various industrial and commercial serial communication systems.
Replacement Considerations
The DS3487T is noted as pin-compatible. Other similar devices include the DS26C31 and ST26C31, which serve comparable functions as quad tri-state differential line drivers.
