It contains two independent elements, each handling four bits, with symmetrical 24 mA source and sink drive. The 4.5 V to 5.5 V supply range places it firmly in 5 V logic systems — not a 3.3 V part. Packaged in a through-hole 20-pin DIP (0.300\" wide, 7.62 mm pitch), it is suited for breadboard prototyping, legacy bus interface cards, and industrial control panels where DIP sockets simplify field replacement. ## Industrial temperature range and deployment context Rated for -40°C to 85°C ambient, the CD74ACT240E covers the industrial temperature grade. This makes it a fit for factory automation cabinets, outdoor telecom equipment, and motor drive interfaces where the board sees seasonal temperature swings but not the full -55°C military floor. ## Sourcing and lifecycle The CD74ACT240E is listed as Active in production. For BOM lines requiring a through-hole 5 V buffer/inverter, this part is a straightforward call — no last-time-buy risk, no legacy-surplus dependency.","metaTitle":"CD74ACT240E Buffer Inverter, 24mA, 20-DIP – 74ACT Series","metaDescription":"CD74ACT240E buffer inverter with 3-state output, 24mA drive, 4.5V–5.5V supply.
