NTE9946 & NTE9949 Integrated Circuit DTL, Quad, 2−Input NAND Gate Description: The NTE9946 and NTE9949 are DTL integrated circuits in a 14−Lead DIP type package consisting of four 2−input NAND gate circuits. These devices can be used as dual 2−input non−inverting gates or as two bistable circuits when two dual 2−input gates are cross−coupled.
