A 14.8 KB PDF datasheet for the SN7430N, a single 8-input positive NAND gate in a plastic DIP package. It covers the pinout, logic function and DC and switching characteristics. The output should only go low when all eight inputs are high, which makes this chip easy to verify with a logic probe when checking address decoding or wide gating on vintage boards. Confirm the logic family printed on the IC before using a substitute from another series.
