DM54LS323/DM74LS323  
8-Bit Universal Shift/Storage Register  
with Synchronous Reset and Common I/O Pins  
General Description  
The ’LS323 is an 8-bit universal shift/storage register with  
Features  
Y
Common I/O for reduced pin count  
Y
TRI-STATE outputs. Its function is similar to the ’LS299  
Four operation modes: shift left, shift right, parallel load  
and store  
É
with the exception of Synchronous Reset. Parallel load in-  
puts and flip-flop outputs are multiplexed to minimize pin  
count. Separate inputs and outputs are provided for flip-  
flops Q0 and Q7 to allow easy cascading. Four operation  
modes are possible: hold (store), shift left, shift right, and  
parallel load. All modes are activated on the LOW-to-HIGH  
transition of the Clock.  
Y
Separate continuous inputs and outputs from Q0 and  
Q7 allow easy cascading  
Y
Y
Fully synchronous reset  
TRI-STATE outputs for bus oriented applications
