Two Line Output Control  
For the most efficient use of these two control  
lines, E should be decoded and used as the prima-  
ry device selecting function, while G should be  
made a common connection to all devices in the  
array and connected to the READ line from the  
system control bus. This ensures that all deselect-  
ed memory devices are in their low power standby  
mode and that the output pins are only active  
when data is required from a particular memory  
device.  
Because OTP EPROMs are usually used in larger  
memory arrays, this product features a 2 line con-  
trol function which accommodates the use of mul-  
tiple memory connection. The two line control  
function allows:  
a. the lowest possible memory power dissipation,  
b. complete assurance that output bus contention  
will not occur.
