8 - BIT SUCCESSIVE APPROXIMATION REGISTER (with  
Expansion Control)  
General Description  
The 'LS503 is an 8-bit register with the interchange logic necessary to perform  
serial-to-parallel conversion and provide an active LOW Conversion Complete (/CC) signal  
coincident with storage of the eighth bit. An active LOW Start (/S) input performs  
synchronous initialization which forces Q7 LOW and all others HIGH. Subsequent clocks  
shift Q7 LOW signal downstream which simultaneously backfills the register such that the  
first serial data (D input) bit is stored in Q7, the second bit in Q6, the third in Q5,  
etc.  
The active LOW Enable (/E) input allows cascading of two or more devices by connecting the  
/E input into the /CC output of a preceding (more significant) device. After a START  
operation, a HIGH signal on /E forces Q7 HIGH and prevents the device from accepting  
serial data. The 'LS503 will remain inhibited intil the device is filled, causing its /CC  
output to go LOW. This LOW signal then enables the 'LS503 to accept the serial data on  
subsequent clocks.
