8-Input Universal Shift/Storage Register  
with Common Parallel I/O Pins  
General Description  
Features  
■ ICC and IOZ reduced by 50%  
The AC/ACT299 is an 8-bit universal shift/storage register  
with 3-STATE outputs. Four modes of operation are possi-  
ble: hold (store), shift left, shift right and load data. The par-  
allel load inputs and flip-flop outputs are multiplexed to  
reduce the total number of package pins. Additional out-  
puts are provided for flip-flops Q0, Q7 to allow easy serial  
■ Common parallel I/O for reduced pin count  
■ Additional serial inputs and outputs for expansion  
■ Four operating modes: shift left, shift right, load  
and store  
■ 3-STATE outputs for bus-oriented applications  
■ Outputs source/sink 24 mA  
cascading. A separate active LOW Master Reset is used to  
reset the register.  
■ ACT299 has TTL-compatible inputs
