For a BOM line that needs a dual 4-input NAND gate in a 14-SOIC footprint, this part is a safe choice for both new builds and repair stock — no LTB risk, no forced redesign to a different logic family. ## Mounting and package — 14-SOIC, surface-mount only The device comes in a 14-SOIC package with a body width of 3.90 mm (0.154\"). It's a surface-mount part — no through-hole variant. The supplier device package is listed as 14-SOIC.","metaTitle":"CD74HCT20MT 74HCT Dual 4-Input NAND Gate, 28ns @ 4.5V","metaDescription":"CD74HCT20MT dual 4-input NAND gate, 74HCT series. 4.5V–5.5V supply, 28ns propagation delay at 4.5V/50pF. -55°C to 125°C range.
