Texas Instruments SN54ALS02A/SN54AS02/SN74ALS02A/SN74AS02 Quadruple 2-Input Positive-NOR Gates Datasheet
The document describes the SN54ALS02A, SN54AS02, SN74ALS02A, and SN74AS02 devices, which contain four independent 2-input positive-NOR gates. These components perform the Boolean functions Y = A+B or Y=AeB in positive logic.
The datasheet details performance specifications for military-grade (SN54) and commercial-grade (SN74) variants across various package options including Plastic Small-Outline, Ceramic Chip Carriers, and standard DIPs. It includes tables for absolute maximum ratings, recommended operating conditions, electrical characteristics over temperature ranges, and switching characteristics with associated test circuit diagrams.
