Quad 2-Input NAND Buffers with 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
