HD74HC323
8-bit Universal Shift/Storage Register (with 3-state Outputs)
REJ03D0610-0200 (Previous ADE-205-489)
Rev.2.00 Jan 31, 2006
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 accomplished by taking both function-select lines S0 and S1 high. This places the threestate outputs in a high-impedance state, which permits data that is applied on the I/O ports to be clocked into the register.
