Inverter Gates Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successors, noting that original Harris assets may have been acquired. Confirm the specific suffix 'EX' corresponds to the 14-DIP through-hole packaging variant. Ensure the component meets the required HCT logic specifications for voltage thresholds and propagation delays. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Inverter Gates Selection Notes

Select this component when a quad NAND gate with open-drain outputs is required for digital logic designs. The HCT series selection ensures compatibility with standard 5V TTL systems. Consider the 14-DIP package for through-hole prototyping or manufacturing needs. Verify that the open-drain nature of the outputs aligns with the pull-up requirements of the target circuit design.
