8-Bit Shift Registers with Output Latches
MM74HC595 8-Bit Shift Registers with Output Latches September 1983 Revised February 1999 MM74HC595 8-Bit Shift Registers with Output Latches The 74HC logic family is speed, function, and pin-out com- General Description patible with the standard 74LS logic family. All inputs are The MM74HC595 high speed shift register utilizes protected from damage due to static discharge by internal advanced silicon-gate CMOS technology. This device pos- diode clamps to V and ground. CC sesses the high noise immunity and low power consump- tion of standard CMOS integrated circuits, as well as the Features ability to drive 15 LS-TTL loads. � Low quiescent current: 80 μA maximum (74HC Series) This device contains an 8-bit serial-in, parallel-out shift reg- ister that feeds an 8-bit D-type storage register. The stor- � Low input current: 1 μA maximum age register has 8 3-STATE outputs. Separate clocks are � 8-bit serial-in, parallel-out shift register with storage provided for both the shift register and the storage register. � Wide operating voltage range: 2V–6V The shift register has a direct-overriding clear, serial input, � Cascadable and serial output (standard) pins for cascading. Both the shift register and storage register use positive-edge trig- � Shift register has direct clear gered clocks. If both clocks are connected together, the � Guaranteed shift frequency: DC to 30 MHz shift register state will always be one clock pulse ahead of the storage register.
