I want to design a selectable input NAND gate using IC 7420 which should work as a 2- or 3-input NAND gate even when 2 or 3 inputs are applied
See how the TS specified a selectable NAND gate, which takes either two or three inputs? Tying some gate inputs high, does not make it selectable. I realize he may have meant use a quad input NAND gate as either 2 or 3 input NAND gate, but we didn't ask him (nor has he returned).I want to design a selectable input NAND gate using IC 7420 which should work as a 2- or 3-input NAND gate even when 2 or 3 inputs are applied
