June 1989
DM5401DM7401 Quad 2-Input NAND Gates
with Open-Collector Outputs
General Description
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 op-
eration
Pull-Up Resistor Equations
RMAX e
VCC (Min) b VOH
N1 (IOH) a N2 (IIH)
RMIN e
VCC (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
