MM74HC595 8-Bit Shift Register with Output Latches June 2009 MM74HC595 8-Bit Shift Register with Output Latches Features Description The MM74HC595 high-speed shift register utilizes Low Quiescent current: 80A Maximum advanced silicon-gate CMOS technology. This device (74HC Series) possesses the high noise immunity and low power Low Input Current: 1A Maximum consumption of standard CMOS integrated circuits, as well as the ability to drive 15 LS-TTL loads. 8-Bit Serial-In, Parallel-Out Shift Register with Storage This device contains an eight-bit serial-in, parallel-out, shift register that feeds an eight-bit D-type storage Wide Operating Voltage Range: 2V6V register. The storage register has eight 3-state outputs. Cascadable Separate clocks are provided for both the shift register and the storage register. The shift register has a direct- Shift Register has Direct Clear overriding clear, serial input, and serial output Guaranteed Shift Frequency: DC to 30MHz (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 is one clock pulse ahead of the storage register. The 74HC logic family is speed, function, and pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to V and ground.
