100322QCX

Overview

The Fairchild Semiconductor 100322QCX is a monolithic quad driver featuring two OR and two NOR outputs with a common enable input. Designed for low power applications, it offers voltage compensated operation within the range of -4.2V to -5.7V. The device provides 2000V ESD protection and includes 50 kΩ pull-down resistors on all inputs. It is pin and function compatible with the 100113 and 100112 series, facilitating direct upgrades or replacements in existing designs requiring reduced power consumption.

Feature Summary

• Monolithic quad driver architecture with integrated OR and NOR logic functions
• Voltage compensated operating range optimized for negative supply voltages
• High electrostatic discharge (ESD) protection rating of 2000V
• Pin and function compatibility with legacy 100113 and 100112 drivers

Applications

• Low power line driving applications
• Systems requiring combined OR/NOR logic buffering
• Upgrades from 100113/100112 based designs
• Industrial environments requiring high ESD robustness

Procurement Notes

Verify the specific suffix 'QCX' against official Fairchild documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS requirements if applicable to your manufacturing standards, as older variants may differ. Cross-reference the datasheet revision date to confirm electrical characteristics match your design constraints.

Selection Notes

Select this component when a quad driver with mixed OR/NOR outputs is required in a compact form factor. It serves as a drop-in replacement for the 100113 and 100112, offering significant power reduction. Consider its voltage compensation range and ESD protection levels when designing for harsh industrial environments or sensitive signal lines.

Part Context

This part belongs to the 1003xx series of low power quad drivers manufactured by Fairchild Semiconductor. It shares architectural similarities with the 100313 but includes specific packaging and reel configurations denoted by the QCX suffix. The series is designed to minimize power dissipation while maintaining signal integrity in digital logic interfaces.

Replacement Considerations

The 100322QCX is explicitly documented as pin and function compatible with the 100113 and 100112. Designers can substitute these legacy parts directly without schematic modifications, provided the power supply and load conditions remain within the specified voltage compensated range.
