74F322
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
parallel load. An asynchronous Master Reset (MR) input
overrides clocked operation and clears the register.
Features
s Multiplexed parallel I/O ports
s Separate serial input and output
s Sign extend function
s 3-STATE outputs for bus applications
