Inverter Gates Procurement Notes

Verify the specific ordering suffix 'E4' against the manufacturer's current orderable addendum to confirm active production status and lead finish specifications. Ensure compatibility with RoHS3 requirements and check for any recent package dimension updates in the latest datasheet revision before finalizing procurement.

Inverter Gates Selection Notes

Select this component when designing systems requiring dual 4-input NAND functionality within the HC logic family. It is suitable for applications needing wide voltage operation between 2 V and 6 V. Consider the thermal resistance characteristics of the SOIC-14 package if high ambient temperatures are expected.

Inverter Gates Part Context

This part belongs to the SNx4HC20 series of dual 4-input NAND gates. It shares functional similarities with other devices in the HC family but is distinguished by its specific input count and packaging. The 'DBRE4' designation indicates a specific tape-and-reel packaging variant with environmental compliance markings.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating. They should be terminated to either VCC or ground using pull-up or pull-down resistors to prevent undefined operational states.

What is the maximum capacitive load recommended?

To ensure optimal performance, the capacitive load at the output should be less than or equal to 70 pF.
