8-Bit Shift Register with Output Latches
MM74HC595
General Description The MM74HC595 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 eight−bit serial−in, parallel−out, shift register that feeds an eight−bit D−type storage register. The storage register has eight 3−state outputs. Separate clocks 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.
