MM74HC595 8-Bit Shift Registers with Output Latches September 1983 Revised July 2004 MM74HC595 8-Bit Shift Registers with Output Latches General Description Features The MM74HC595 high speed shift register utilizesLow quiescent current: 80 μA maximum (74HC Series) advanced silicon-gate CMOS technology. This device pos-Low input current: 1 μA maximum sesses the high noise immunity and low power consump- 8-bit serial-in, parallel-out shift register with storage tion of standard CMOS integrated circuits, as well as the Wide operating voltage range: 2V–6V ability to drive 15 LS-TTL loads. Cascadable This device contains an 8-bit serial-in, parallel-out shift reg- Shift register has direct clear ister that feeds an 8-bit D-type storage register. The stor- age register has 8 3-STATE outputs. Separate clocks areGuaranteed shift frequency: DC to 30 MHz 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 trig- gered clocks. If both clocks are connected together, the shift register state will always be one clock pulse ahead of the storage register. The 74HC logic family is speed, function, and pin-out com- patible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to V and ground.
