54F 74F299 Octal Universal Shift Storage Register
with Common Parallel I O Pins
General Description
The ’F299 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 Additional outputs
Q0 – Q7 are provided to allow easy serial cascading A sep-
arate active LOW Master Reset is used to reset the register
Features
Y Common parallel I O for reduced pin count
Y Additional serial inputs and outputs for expansion
Y Four operating modes shift left shift right load and
store
Y TRI-STATE outputs for bus-oriented applications
Y Guaranteed 4000V minimum ESD protection
