100302SC

Overview

The Fairchild Semiconductor 100302SC is a monolithic quint 2-input OR/NOR gate belonging to the 100K series. It features five independent logic circuits with a common enable input. Each input includes an internal 50 kΩ pull-down resistor, ensuring defined logic states when unconnected. The device operates within a supply voltage range of 2V to 6V and supports data rates up to 40 MHz. It is housed in a 24-pin SOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Configurable as either OR or NOR logic function via a single control pin
• Integrated 50 kΩ pull-down resistors on all inputs for noise immunity
• Monolithic construction providing five independent 2-input gates in one package

Applications

• Digital logic signal processing
• Data acquisition systems
• Industrial control interfaces
• Communication equipment logic stages

Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any electrical parameter updates. Ensure storage conditions meet semiconductor specifications to prevent degradation before installation.

Selection Notes

Select this component when multiple configurable OR/NOR gates are required in space-constrained designs. The common enable feature allows synchronized control of all five channels. Consider the 100K series speed and power characteristics against alternative logic families for compatibility with existing circuit voltages and timing requirements.

Part Context

This part belongs to Fairchild's legacy 100K series of low-power Schottky TTL-compatible logic devices. The 100302 variant specifically integrates five dual-input gates into a single integrated circuit. It represents a standard solution for complex logic implementation prior to the widespread adoption of more advanced CMOS technologies.
