74F323
Octal Universal Shift/Storage Register
with Synchronous Reset and Common I/O Pins
General Description
The 74F323 is an 8-bit universal shift/storage register with
3-STATE outputs. Its function is similar to the 74F299 with
the exception of Synchronous Reset. Parallel load inputs
and flip-flop outputs are multiplexed to minimize pin count.
Separate serial inputs and outputs are provided for Q
0
and
Q
7
to allow easy cascading. Four operation modes are
possible: hold (store), shift left, shift right and parallel load.
Features
a73 Common parallel I/O for reduced pin count
a73 Additional serial inputs and outputs for expansion
a73 Four operating modes: shift left, shift right, load and
store
a73 3-STATE outputs for bus-oriented applications

Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
