Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Confirm that the specific 'PC' suffix corresponds to the PDIP-14 package variant. Ensure the component meets the required operating temperature range and voltage specifications for your design environment before procurement.

Selection Notes

Select this component when a dual 4-input NAND configuration is required in a through-hole DIP package. It serves as a pin-compatible alternative to low-power Schottky TTL (LSTTL) devices while offering lower power consumption. Verify compatibility with system voltage levels, specifically ensuring the 2.0 V to 6.0 V range aligns with the application requirements.

Part Context
