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
é
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,

, are provided to allow easy serial cascading. A sep-
arate active LOW Master Reset is used to reset the register.
Features
Y
