产品描述

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.
