DM54LS299 DM74LS299
8-Input Universal Shift Storage Register
with Common Parallel I O Pins
General Description
The 鈥橪S299 is an 8-bit universal shift storage register with
TRI-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 re-
duce the total number of package pins Separate outputs
are provided for flip-flops Q0 and Q7 to allow easy cascad-
ing A separate active LOW Master Reset is used to reset
the register
