Octal Serial/Parallel Register with Sign Extend
General Description
The 74F322 is an 8-bit shift register with provision for either
serial or parallel loading and with 3-STATE parallel outputs
plus a bi-state serial output. Parallel data inputs and paral-
lel 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
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
