Product Overview
The Texas Instruments SN74H11J is a vintage high-speed TTL integrated circuit housing three independent 3-input positive-AND gates in a hermetic 14-pin ceramic dual in-line package (CDIP-14). Designed for 5-volt TTL logic architectures, the 74H series offers faster switching transitions than standard 7400 series logic while maintaining full pin-for-pin functional compatibility.
Key Features
- Triple independent 3-input positive-AND logic gates
- 5.0V nominal logic supply voltage (4.75V to 5.25V operating range)
- High-speed 54H/74H series TTL logic family
- 14-pin ceramic dual in-line package (CDIP-14)
- Date code marking 7024A
- Standard through-hole DIP footprint for breadboard and socket installation
Applications
- Restoring vintage computing, test equipment, and industrial control logic cards from the 1970s
- Replacing damaged 74H11 or 7411 logic gates on through-hole printed circuit boards
- Breadboard prototyping for hardware logic experiments and retrocomputing projects
Frequently Asked Questions
What logic function does the SN74H11J provide?
The chip contains three separate 3-input positive-AND gates. Each gate performs the Boolean function Y = A • B • C at standard 5-volt TTL levels.
What package type is used for this IC?
The J suffix indicates a 14-pin hermetic ceramic dual in-line package (CDIP-14) with through-hole leads.
Are the leads straight?
These parts were originally stored loose, so some leads may be slightly bent. They can be carefully straightened with fine-nose pliers before socket insertion.
Why buy individual SN74H11J chips here instead of an unverified bulk lot?
You can buy the exact count needed for your repair or build without paying for surplus lots packed with unused extras. If you need several gates for a larger layout, more pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, or free once your cart reaches $28, with same or next business day dispatch from our Idaho warehouse.
