MM74HC594 8-Bit Shift Register with Output Registers MM74HC594 8-Bit Shift Register with Output Registers This high speed shift register utilizes advanced silicon-gate CMOS technology. This device possesses the high noise immunity and low power consumption of standard CMOS integrated circuits, as well as the ability to drive 15 LS-TTL loads. This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Separate clocks and direct overriding clears are provided for both the shift register and the storage register. The shift register has a direct-overriding clear, serial input, and serial output standard pins for cascading. Both the shift register and storage register use positive-edge triggered clocks. If both clocks are connected together, the shift register state will always be one clock pulse ahead of the storage register.
