5409FMQB
Description
This device contains four independent gates each of which performs the logic AND function The open-collector outputs require external pull-up resistors for proper logical operation
Pull-Up Resistor Equations
RMAX e VCC (Min) b VOH N1 (IOH) a N2 (IIH)
VCC (Max) b VOL RMIN e 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
