| Manufacturer | Fairchild Semiconductor |
| Overview | This device contains four independent gates each of which performs the logic NAND function. The open-collector outputs require external pull-up resistors for proper logical operation. These gates feat. high-voltage output ratings (up to 15V) for interfacing with 12V systems. Although the outputs are rated for 15V, the device supply is still rated for 5V. Pull-Up Resistor Equations Where: N1 (IOH) = total maximum output high current for all outputs tied to pull-up resistor N2 (IIH) = total maxim. |
