100391PC

Overview

The Fairchild Semiconductor 100391PC is a mixed-signal translator IC designed to convert TTL input signals to PECL output signals. It features one circuit with six channels per circuit, housed in a 24-pin PDIP package. This device serves as a unidirectional level shifter for interfacing between different logic families.

Feature Summary

• Converts TTL input signals to PECL output signals
• Unidirectional signal translation capability
• Six-channel configuration within a single circuit

Applications

• Interfacing TTL logic circuits with PECL systems
• Level shifting in mixed-signal digital designs
• Signal translation in high-speed data transmission interfaces

Procurement Notes

Verify the exact datasheet specifications from Fairchild Semiconductor or authorized distributors before procurement. Confirm that the 24-PDIP package and unidirectional TTL-to-PECL functionality align with your design requirements. Ensure compatibility with your system's voltage levels and signal integrity needs.

Selection Notes

Select this component when TTL-to-PECL conversion is required in a unidirectional manner. Consider the six-channel capacity and PDIP packaging constraints. Evaluate if the specific voltage thresholds and speed characteristics meet your application's performance criteria compared to alternative translators.

Part Context

The 100391PC belongs to Fairchild Semiconductor's family of mixed-signal translators. It complements other devices like the 100390PC, which handles PECL-to-TTL conversion. These components facilitate interoperability between different logic standards in complex electronic systems.

Replacement Considerations

Check for direct substitutes such as the 100390PC if bidirectional or reverse conversion is needed. Verify pinout compatibility and electrical characteristics against equivalent parts from other manufacturers offering TTL-to-PECL translation in similar packages.
