54F 74F322
Octal Serial Parallel Register with Sign Extend
General Description
The ’F322 is an 8-bit shift register with provision for either
serial or parallel loading and with TRI-STATE parallel out-
puts plus a bi-state serial output Parallel data inputs and
parallel outputs are multiplexed to minimize pin count State
changes are initiated by the rising edge of the clock Four
synchronous modes of operation are possible hold (store)
shift right with serial entry shift right with sign extend and
parallel load An asynchronous Master Reset (MR) input
overrides clocked operation and clears the register
Features
Y Multiplexed parallel I O ports
Y Separate serial input and output
Y Sign extend function
Y TRI-STATE outputs for bus applications
