The -2 suffix is the 150 ns speed grade. Published 4116-family equivalents include the TMS4116 (Texas Instruments), MCM4116 (Motorola), μPD416 (NEC), TMM416 (Toshiba), AM9016 (AMD), and MB8116 (Fujitsu). Always confirm speed grade, supply voltages, and timing against your equipment before substituting.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ\u0026amp;A\u003c\/strong\u003e\u003cbr\u003eQ: What is the Mostek MK4116N-2GP? A: A 16,384 x 1-bit dynamic RAM with a 150 ns maximum access time in a 16-pin plastic DIP, date code 7918.\u003cbr\u003eQ: What supply voltages does the MK4116 require? A: +12V (VDD), +5V (VCC), and −5V (VBB).\u003cbr\u003eQ: Why is this chip discontinued? A: The 64K DRAM generation moved to 5V-only operation, superseding 12V\/±5V 16K parts like the MK4116, and Mostek has been defunct since 1985. Remaining supply is new old stock.\u003cbr\u003e\u003cbr\u003eMostek MK4116N-2GP MK4116N-2 MK4116N2GP MK4116 4116N 4116 DRAM Mostek Memory IC 16Kx1 DRAM 16K DRAM 16384x1 Memory 150ns DRAM Page Mode RAM RAS Refresh Dynamic RAM PDIP-16 DIP-16 16 Pin IC Through Hole Memory Chip Discontinued IC Obsolete Semiconductor New Old Stock NOS Vintage Electronics Vintage Computer Parts 1979 Integrated Circuit Retro Computer RAM Apple II Memory TRS-80 Memory ZX Spectrum RAM Commodore PET RAM IBM PC Memory Arcade Machine RAM Legacy Memory Circuit Board Repair Computer Restoration Malaysia Semiconductor\u003cbr\u003e\u003cbr\u003eThank you for shopping with American Industrial Parts Group!","brand":"Mostek","offers":[{"title":"Default Title","offer_id":49598944510107,"sku":"MOS-MK4116N-2GP-N","price":6.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/0857\/7435\/files\/mostek-mk4116n-2gp-vintage-dram-ic-1-american-industrial-parts-group.png?v=1790019953","url":"https:\/\/americanindustrialpartsgroup.com\/products\/mostek-mk4116n-2gp-16kx1-150ns-dram-dip-16-nos-vintage-1979-ic","provider":"American Industrial Parts Group","version":"1.0","type":"link"}
