HD74HC323 Datasheet | Hitachi Semiconductor

8-bit Universal Shift/Storage Register (with 3-state Outputs) Description This eight-bit universal register Features multiplexed I/O ports to achieve full eight bit data handling in a single 20-pin package. HD74HC323 applications are as stacked or push-down registers, buffer storage, and accumulator registers. Two function-select inputs and two output control inputs can be used to choose the modes of operation listed in the function table. Synchronous parallel loading is acplished by taking both function-select lines S0 and S1 high. This places the three-state outputs in a high-impedance state, which permits data that is applied on the I/O ports to be clocked into the...
