54F74F322

Octal SerialParallel 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
