100391SC

Overview

The Fairchild Semiconductor 100391SC is a low-power, single-supply hex TTL-to-PECL translator housed in a 24-SOP package. It provides unidirectional signal translation for six channels within a single integrated circuit. The device operates across a temperature range of 0°C to 85°C and is designed for surface-mount applications.

Feature Summary

• Unidirectional level shifting from TTL logic levels to PECL standards
• Single power supply operation for simplified circuit design
• Low power consumption characteristics suitable for energy-efficient systems

Applications

• TTL to PECL interface conversion
• High-speed digital signal translation
• Communication system level shifting

Procurement Notes

Verify the specific suffix 'SC' against the manufacturer's current datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the 24-SOP package dimensions align with your PCB footprint. Confirm that the operating temperature range meets your environmental constraints before finalizing procurement.

Selection Notes

Select this component when unidirectional translation from TTL inputs to PECL outputs is required. Consider the single-supply capability if power distribution is limited. Evaluate the channel count to ensure it matches the number of signals needing translation without requiring additional discrete components or multiple ICs.

Part Context

This part belongs to the family of mixed-signal translators and level shifters produced by Fairchild Semiconductor. These devices facilitate interoperability between different logic families, enabling seamless integration of TTL-based controllers with PECL-based high-speed peripherals in complex electronic systems.

Replacement Considerations

Check for direct substitutes such as the 100391QI, ensuring functional equivalence and package compatibility. Verify that any alternative maintains the same unidirectional TTL-to-PECL translation capability and operating voltage ranges.
