DS96F174CN

Overview

The DS96F174CN is a quad differential driver manufactured by Texas Instruments, belonging to the National Semiconductor product lineage acquired by TI. It is designed for EIA-485 and EIA-422 communication standards. The component features four independent differential drivers in a single package. It operates within a supply voltage range of 3.0 V to 5.5 V. The device supports data transmission rates up to 10 Mbps. It utilizes a standard SOIC-16 surface-mount package. The operational temperature range extends from 0°C to +70°C. The inputs are compatible with TTL logic levels.

Feature Summary

• Provides four independent differential driver channels for robust signal transmission.
• Supports both EIA-485 and EIA-422 bus communication protocols.
• Features TTL-compatible input logic for easy interface with digital systems.
• Designed for high-speed data transfer applications requiring differential signaling.

Applications

• RS-485 multi-drop communication networks
• EIA-422 point-to-point or multi-point links
• Industrial control system data buses
• Building automation and security systems

Procurement Notes

Verify the manufacturer marking on the component body to confirm it originates from Texas Instruments, as this part was originally produced by National Semiconductor prior to acquisition. Ensure the suffix 'CN' corresponds to the specific SOIC-16 package and commercial temperature grade required for your design. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select this component when a quad differential driver is needed for RS-485 or RS-422 interfaces. It is suitable for designs requiring TTL input compatibility and operation within the commercial temperature range. Consider alternative packages if lead-free requirements or different thermal profiles are necessary, as the CN suffix denotes a specific plastic small-outline package variant.

Part Context

This component is part of the DS96F17x family of differential transceivers. It serves as the driver counterpart to receivers like the DS96F173. The series is widely used in legacy and modern industrial electronics where reliable half-duplex or full-duplex serial communication is required over twisted-pair cabling.

Replacement Considerations

Direct substitutes include the DS96F174CJ (SOIC-16) and DS96F174ME/883 (MIL-STD-883 qualified). Generic equivalents may include the MAX1348E or SN75176B, though pinouts and electrical characteristics should be verified against the original datasheet before substitution.
