SHIFT REGISTER, 8BIT, SISO/PISO, SOIC-16; Logic Family / Base Number: 74HC589; Shift Register Function: Parallel to Serial, Serial to Serial; No. of Elements: 1 Element; No. of Bits Per Element: 8bit; Logic Case Style: SOIC;
High-Performance Silicon-Gate CMOS The MC74HC589A is similar in function to the HC597 which is not a 3-state device. The device inputs are compatible with standard CMOS outputs with pullup resistors they are compatible with LSTTL outputs. This 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 Function Table). The shift register output QH is a three-state output allowing this device to be used in bus-oriented systems. The HC589A directly interfaces with the Motorola SPI serial data port on CMOS MPUs and MCUs.
