Product details

Dual 4-input NAND gate in LS TTL

The 74LS20PC is a dual 4-input NAND gate from the low-power Schottky (LS) TTL family. It contains two independent NAND gates, each with four inputs, in a single package. This is a standard logic function used for gating, decoding, and combinatorial logic in 5 V TTL systems.

Active lifecycle — still in production

No end-of-life notice or last-time-buy has been issued for this part.

Bulk packaging — shelf-friendly for MRO

This part is — loose units in an anti-static bag or tube, not taped and reeled. For storeroom and MRO buyers, Bulk means no dry-pack concerns (no MSL bake required before use) and easy single-unit kitting. Store in a dry, ESD-safe cabinet; the parts are not moisture-sensitive out of the bag.

Frequently asked questions

What is the equivalent of 74LS20PC?

The 74LS20PC is a dual 4-input NAND gate in LS TTL. A functional equivalent in a different logic family would be the 74F00 (quad 2-input NAND) or 74AC11004 (hex inverter), but neither is a direct pin-for-pin substitute. For a same-function LS TTL replacement, look for any standard 74LS20 in a DIP package; the 74LS20PC is the standard PDIP variant.
