SN74ALS10A/ALS10 devices integrate three independent 3-input positive-NAND gates, providing positive-logic outputs where Y implements either A•B•C or A+B+C. The SN54ALS10A and SN54AS10 variants are specified for full military temperature operation from −55°C to 125°C, while SN74ALS10A and SN74AS10 operate from 0°C to 70°C. The document lists function truth tables, top-view pinouts for multiple packages (D, J, N, FK) and key electrical and switching characteristics, including absolute maximum ratings, recommended operating conditions, and timing parameters.

FAQs

What logic functions do the SN74ALS10 family gates implement?

Each device contains three independent 3-input positive-NAND gates. In positive logic, the output Y corresponds to either Y = A•B•C or Y = A + B + C depending on the described positive-logic formulation in the document.

What are the operating temperature ranges for the SN54 and SN74 versions?

The SN54ALS10A and SN54AS10 are specified over −55°C to 125°C. The SN74ALS10A and SN74AS10 are specified from 0°C to 70°C.

Which package types are supported and how are pin numbers indicated?

Package options include small-outline (D), ceramic chip carriers (FK), and standard plastic (N) and ceramic (J) 300-mil DIPs. The pin numbers shown correspond to the D, J, and N packages, with top-view diagrams provided for the listed package types.
