Procurement Notes

Verify that the specific QC suffix corresponds to the required industrial grade temperature rating, as packaging variants may differ. Confirm the lead-free status and RoHS compliance against current manufacturing standards. Ensure the procurement channel sources genuine Fairchild Semiconductor components to guarantee the specified 2000V ESD protection levels are maintained. Cross-reference the datasheet revision date to confirm compatibility with existing system designs.

Selection Notes

Select this component when designing systems requiring simultaneous OR and NOR logic generation from a single package. It is suitable for applications needing reduced power consumption compared to older generations like the 100113. Consider its pin compatibility with existing 100112 or 100113 footprints if upgrading legacy hardware. Evaluate the -4.2V to -5.7V operating range to ensure alignment with the target system's negative power supply rails.
