Each is marked \"9N23\/7423\" with Fairchild's \"PC F\" marking. Photos show a representative unit with date code 7304, which places manufacture in 1973; date codes may vary within the lot. Never installed. Leads show light storage discoloration, as pictured.\u003cbr\u003e\u003cbr\u003eFairchild sold its 7400-series equivalents under its own 9N numbering, so these parts carry both the Fairchild 9N23 number and the industry-standard 7423 number.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003eTwo 4-input NOR gates, each with a strobe input\u003cbr\u003eStandard 7400-series TTL, 5V logic\u003cbr\u003e16-pin plastic DIP, through-hole\u003cbr\u003eOriginal Fairchild manufacture, 1970s vintage\u003cbr\u003eCommercial temperature range, 0°C to 70°C\u003cbr\u003e10 pieces\u003cbr\u003e\u003cbr\u003eCompatibility:\u003cbr\u003eDirect replacement for 7423, SN7423, and Fairchild 9N23 in 16-pin DIP sockets. The 7425 performs the same dual 4-input NOR-with-strobe function but is a 14-pin part, so it is not a drop-in substitute.\u003cbr\u003e\u003cbr\u003eQ\u0026amp;A\u003cbr\u003eQ: What is the 9N23\/7423?\u003cbr\u003eA: A Fairchild dual 4-input NOR gate with strobe, in standard TTL, packaged in a 16-pin plastic DIP.\u003cbr\u003eQ: What replaces a 7423?\u003cbr\u003eA: These parts are a direct replacement for 7423, SN7423, and Fairchild 9N23.\u003cbr\u003eQ: Is the 7423 the same as the 7425?\u003cbr\u003eA: Same logic function, different package. The 7423 is 16-pin; the 7425 is 14-pin. They are not pin-compatible.\u003cbr\u003eQ: How old are these parts?\u003cbr\u003eA: The pictured unit is date coded 7304, which places manufacture in 1973.
