DM7426 Quad 2-Input NAND Gates with High Voltage Open-Collector Outputs General Description Pull-Up Resistor Equations This device contains four independent gates each of which performs the logic NAND function. The open-collector out- puts require external pull-up resistors for proper logical operation.
Where: N1 (IOH) = total maximum output high current
for all outputs tied to pull-up resistor
N2 (IIH) = total maximum input high current for
all inputs tied to pull-up resistor N3 (IIL) = total maximum input low current for all inputs tied to pull-up resistor
