SN7428N
Quadruple 2-input positive-NOR buffer logic IC engineered with high-current output gates to handle low-impedance bus lines. | 14-Pin Plastic DIP | Industrial programmable logic controller (PLC) cabinets, automated machine tool panels, commercial building automation enclosures. | SN7428N | NTE7428 | SK7428 | 7428, SN7428AN, MC7428P, DM7428N, Texas Instruments 7428 | Diagnostic Test-Bench Signal Splitter: Wired into a handheld troubleshooting box running on a dual-rail power supply to safely buffer and split a master timing frequency into four parallel diagnostic channels. | Texas Instruments High-Drive Logic Networks: Engineered with extra power drive margins to safely pull down high-capacitance loads, these heavy-duty NOR gates were regularly designed into the master reset distribution networks of Ampex professional reel-to-reel tape decks and memory expansion chassis for early Control Data Corporation (CDC) mainframe peripherals.
