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 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 registers.

TYPICAL  
SUPPLY CURRENT  
(TOTAL)  
The 74F322 contains eight D-type edge triggered flip-flops and the  
interstage gating required to perform right shift and the intrastage  
gating necessary for hold and synchronous parallel load operations.  
A Low signal on RE enables shifting or parallel loading, while a High  
signal enables the hold mode. A High signal on S/P enables shift  
right, while a Low signal disables the 3-State output buffers and  
enables parallel loading. In the shift right mode a High signal on SE  
enables serial entry from either D0 or D1, as determined by the S  
input. A Low signal on SE enables shift right, but Q7 reloads its  
contents, thus performing the sign extend function. A High signal on  
OE disables the 3-State output buffers, regardless of the other  
control inputs. In this condition the shifting and loading operations  
can still be performed.
