7900901CA

Overview

The Texas Instruments 7900901CA is a dual differential line driver housed in a 14-lead ceramic dual in-line package (CDIP). It operates within an extended temperature range of -55°C to +125°C and requires a supply current of 36 mA. The component supports bipolar logic families and provides two independent drivers for signal transmission applications requiring robust line driving capabilities.

Feature Summary

• Dual channel configuration for simultaneous differential signal processing
• Extended military-grade temperature operation from -55°C to +125°C
• Bipolar technology construction for reliable high-speed switching

Applications

• Industrial communication bus interfaces
• Military aerospace data transmission systems
• High-reliability telemetry link drivers

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm exact electrical tolerances and testing standards. Ensure the CDIP package variant matches the target PCB footprint requirements. Cross-reference the active status with current production lists to avoid obsolete stock issues during integration planning.

Selection Notes

Select this component when bipolar line driver performance is required for harsh environmental conditions. The dual-channel architecture reduces board space compared to single-driver solutions. Confirm that the 14-pin CDIP form factor aligns with existing through-hole manufacturing processes and thermal management strategies for the final assembly.

Part Context

This part belongs to the SN55183/SN75183 family of dual differential line drivers manufactured by Texas Instruments. It serves as a ruggedized alternative for applications demanding high noise immunity and long-distance signal integrity. The device complements receiver counterparts to form complete bidirectional communication links in industrial settings.

Replacement Considerations

The SNJ55183J and SN55183J are documented public substitutes offering identical functional specifications. Verify pin compatibility and package dimensions before substitution to ensure seamless mechanical integration without redesigning the host circuit board layout.
