DM7426
DM7426 is Quad 2-Input NAND Gates manufactured by National Semiconductor.
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
RMAX e
VO (Min) b VOH N1 (IOH) a N2 (IIH)
RMIN e
VO (Max) b VOL IOL b N3 (IIL)
Where N1 (IOH) e total maximum output high current for all outputs tied to pull-up resistor
N2 (IIH) e total maximum input high current for all inputs tied to pull-up resistor
N3 (IIL) e total maximum input low current for all inputs tied to pull-up resistor
