DM74LS299
8-Input Universal Shift/Storage Register with
Common Parallel I/O Pins
General Description
The DM74LS299 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. 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.
