8-Input Universal Shift/Storage Register
with Common Parallel I/O Pins
General Description
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 Q

to allow easy serial
cascading. A separate active LOW Master Reset is used to
reset the register.
