description
This 8-bit universal register features multiplexed I/O ports to achieve full 8-bit data handling in a single 20-pin
package. Two function-select (S0, S1) and two output-enable (OE1, OE2) inputs can be used to choose the
modes of operation listed in the function table.
Synchronous parallel loading is accomplished by taking both S0 and S1 high. This places the 3-state outputs
in a high-impedance state and permits data that is applied on the I/O ports to be clocked into the register.
Reading out of the register can be accomplished while the outputs are enabled in any mode. Clearing occurs
synchronously when the clear (CLR) input is low. Taking either OE1 or OE2 high disables the outputs but this
has no effect on clearing, shifting, or storage of data.
The SN74F323 is characterized for operation from 0
°C to 70°C.

NOTE: a ...h = the level of the steady-state input at inputs A through H, respectively. These data inputs are loaded into the flip-flops while the
flip-flop outputs are isolated from the I/O terminals.
When one or both output-enable inputs are high the eight I/O terminals are disabled to the high-impedance state; however, sequential operation
or clearing of the register is not affected.
