DS96174CN/NOPB

Overview

The DS96174CN/NOPB is a quad differential line driver manufactured by Texas Instruments, designed for RS-422 and RS-485 communication standards. It operates with a single 5V supply voltage and supports data rates up to 10 Mbps. The device features four independent drivers in a 16-pin DIP package, providing robust signal transmission for industrial applications. This component is currently obsolete and no longer in production.

Feature Summary

• Supports RS-422 and RS-485 communication protocols
• Provides four independent differential line drivers
• Operates on a standard 5V power supply
• Housed in a through-hole 16-pin DIP package

Applications

• Industrial control systems requiring RS-485 bus connectivity
• Multi-drop communication networks using RS-422 standards
• Data acquisition systems with long-distance signal transmission needs

Procurement Notes

This component is officially listed as obsolete and is no longer manufactured by Texas Instruments. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the specific manufacturing date code and condition before purchase, as availability is limited and subject to existing inventory levels.

Selection Notes

Engineers selecting this part should consider its obsolete status when designing new products. While suitable for legacy system maintenance, new designs should utilize current Texas Instruments equivalents that offer improved performance or availability. Verify pin compatibility and electrical specifications against modern alternatives to ensure seamless integration without redesigning the entire interface circuitry.

Part Context

The DS96174 series belongs to Texas Instruments' family of RS-422/RS-485 interface devices. These components are widely used in environments requiring reliable serial communication over moderate distances. The CN/NOPB suffix indicates a lead-free, RoHS-compliant version packaged in a standard dual in-line format, historically popular for prototyping and older industrial equipment.

Replacement Considerations

Official substitutes include the SN75174N, which serves as a similar functional replacement. Users should verify pinout compatibility and electrical characteristics between the obsolete DS96174CN/NOPB and potential substitute parts to ensure proper operation in existing circuits.
