DM5438/DM7438 Quad 2-Input NAND Buffers  
with Open-Collector Outputs  
General Description  
Pull-Up Resistor Equations  
b
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.
