MM74HC589 8-Bit Shift Registers with Input Latches and 3-STATE Serial Output
General Description
The MM74HC589 high speed shift register utilizes advanced silicon-gate CMOS technology to achieve the high noise immunity and low power consumption of standard CMOS integrated circuits, as well as the ability to drive 15 LS-TTL loads. The MM74HC589 comes in a 16-pin package and consists of an 8-bit storage latch feeding a parallel-in, serial-out 8bit shift register. Data can also be entered serially the shift register through the SER pin. Both the storage register and shift register have positive-edge triggered clocks, RCK and SCK, respectively.
