DM74LS503  
8-Bit Successive Approximation Register  
(with Expansion Control)  
General Description  
Features  
The DM74LS503 register has an active LOW Enable (E)  
input that is used in cascading two or more packages for  
longer word lengths. A HIGH signal on E, after a START  
operation, forces Q7 HIGH and prevents the device from  
accepting serial data. With the E input of an DM74LS503  
connected to the CC output of a preceding (more signifi-  
cant) device, the DM74LS503 will be inhibited until the pre-  
ceding device is filled, causing its CC output to go LOW.  
This LOW signal then enables the DM74LS503 to accept  
the serial data on subsequent clocks.  
Performs serial-to-parallel conversion  
Expansion control for longer words  
Storage and control for successive approximation A to D  
conversion
