DS75108N

Overview

The DS75108N is a dual differential line driver manufactured by National Semiconductor, now part of Texas Instruments. It features two independent drivers capable of transmitting data over balanced transmission lines. The device operates with a single 5V supply and supports high-speed digital communication protocols. It is housed in a standard 16-pin plastic DIP package, suitable for through-hole mounting on printed circuit boards. The component provides robust signal integrity for point-to-point or multi-drop configurations in industrial and commercial environments.

Feature Summary

• Dual independent differential line drivers
• Single 5V power supply operation
• High-speed data transmission capability
• Standard 16-pin DIP packaging

Applications

• Balanced transmission line interfacing
• Industrial control systems
• Data communication networks
• Multi-drop bus architectures

Procurement Notes

Verify the manufacturer origin as National Semiconductor or Texas Instruments, noting that National Semiconductor was acquired by TI. Confirm the package type is 16-pin DIP and the operating voltage is 5V. Check for RoHS compliance status if required by specific project regulations, as older stock may differ from current production runs.

Selection Notes

Select this component when dual differential signaling is required for noise-immune data transmission. Ensure the system design accommodates the 16-pin DIP footprint and 5V logic levels. Compare against similar devices like the SN55110A for pin compatibility and electrical characteristics if alternative sourcing is necessary.

Part Context

This component belongs to the DS75xx series of line drivers, widely used for RS-422/RS-485 compatible interfaces. National Semiconductor developed these parts before its acquisition by Texas Instruments, which continues to support the product line. The DS75108N specifically offers dual channels for efficient board space utilization in communication modules.

Replacement Considerations

The SN55110A is a documented equivalent dual line driver from Texas Instruments. Verify pinout compatibility and electrical specifications before substitution. Other variants in the DS7511x series may offer tri-state outputs but require interface adjustments.
