SN7400N
by TI(德州仪器)Four two-input NAND gates make the Texas Instruments SN7400N a basic building block for combinational logic. A NAND output goes low only when both inputs are high, allowing the device to implement inverted conditions or form larger logic networks. This version uses through-hole mounting, with 14 pins in the schematic symbol and 14 pads in the PCB footprint. The free file set includes that symbol, PDIP-14_L19.3-W6.4-P2.54-LS7.9-BL-1 footprint and a 3D model. It comes from an actual ProtoFlow import that was converted and checked in the editor. Open the SN7400N directly in ProtoFlow.
