DS96173CN/NOPB

Overview

The DS96173CN/NOPB is a quad differential receiver manufactured by Texas Instruments, designed for high-speed data transmission over twisted-pair cables. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 25 Mbps. The device features EIA-422/EIA-485 compatibility, providing robust signal integrity in noisy environments. Packaged in a standard 16-pin DIP or SOIC format, it offers low power consumption and wide common-mode rejection capabilities, making it suitable for industrial communication applications requiring reliable differential signaling.

Feature Summary

• Quad differential receiver architecture supporting multiple bus nodes
• EIA-422 and EIA-485 interface compliance for standardized communication
• Wide common-mode rejection ratio ensuring noise immunity
• Low power operation compatible with 3.3V and 5V logic systems

Applications

• Industrial automation control networks
• Building automation and security systems
• Data acquisition systems requiring long-distance communication

Procurement Notes

Verify the specific package variant (DIP or SOIC) against the schematic requirements before ordering. Confirm that the operating temperature range meets the environmental specifications of the target application. Ensure that the supply voltage levels align with the system's power rails to prevent damage or malfunction during integration.

Selection Notes

Select this component when a quad receiver topology is required for RS-422 or RS-485 buses. Consider the pinout compatibility with existing PCB layouts if replacing legacy components. Evaluate the need for additional termination resistors based on cable length and data rate to maintain signal quality across the network.

Part Context

This part belongs to the DS96F17x series of differential receivers from Texas Instruments. It serves as a core component for creating multi-drop communication networks where signal integrity is critical. The NOPB suffix indicates lead-free construction, adhering to RoHS standards for environmentally compliant manufacturing processes.

Replacement Considerations

Direct replacements include the DS96173CN and DS96173N variants from National Semiconductor or Texas Instruments. Cross-reference pinouts and electrical characteristics carefully to ensure functional equivalence in existing designs.
