DM7401 - Quad 2-Input NAND Gates with Open-Collector Outputs
National Semiconductor (now Texas Instruments)
General Description
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
Pull-Up Resistor Equations
