The MC74HC589A device consists of an 8−bit storage latch which
feeds parallel data to an 8−bit shift register. Data can also be loaded
serially (see the Function Table). The shift register output, Q_H, is a
3−state output, allowing this device to be used in bus−oriented
systems.
The HC589A directly interfaces with the SPI serial data port on
CMOS MPUs and MCUs.
