SN15837N

💡 Quadruple 2-input NOR gate digital logic IC constructed with an early low-delay bipolar transistor architecture. | 14-Pin Plastic DIP | Mid-century industrial control matrices, early mainframe logic frames, vintage arcade scoring nodes. | SN15837N | NTE7402 | SK7402 | SN7402N, SN15324N, 7402, MC7402P | Multi-Contact Alarm Hub: Combines inputs from four independent door perimeter limit switches into a single NOR tracking point, driving a master warning buzzer high if any entry loop breaks open. | Foxboro Industrial Automation Frameworks and Westinghouse Power Grid Monitor Bays: This legacy boolean gating element was manufactured by Texas Instruments to process discrete safety interlock tracking routines in heavy assembly facilities.
