description
These 8-bit universal shift/storage registers
feature multiplexed input/output (I/O) ports to
achieve full 8-bit data handling in a 20-pin
package. Two function-select (S0, S1) inputs 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 the high-impedance state and permits data 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 has
no effect on clearing, shifting, or storing data.
The SN54ALS323 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C. The
SN74ALS323 is characterized for operation from 0
°
C to 70
°
C.
