SN15846N

💡 Quadruple 2-input NAND buffer IC engineered with a rugged high-current output drive capable of switching heavy external logic rows. | 14-Pin Plastic DIP | Early mainframes, legacy automated telecommunication routing hubs, vintage pinball diagnostic frames. | SN15846N | NTE7440 | SK7440 | SN7440N, 7440, MC7440P, DM7440N | High-Current Diagnostic Indicator Driver: Sinks up to 40mA of continuous current per gate directly through old high-draw incandescent indicator bulbs, allowing active logic states to be checked visually without overloading the chip. | Digital Equipment Corporation (DEC) PDP-Series Minicomputers and SPERRY-UNIVAC Mainframe Enclosures: This heavy-duty driver stage was engineered by Texas Instruments to confidently route logic data through lengthy backplane wiring paths without encountering signal degradation.
