74HC595D / 74HC595V / 74HC595P
8-Bit Shift Registers with Output Latches
General Description
The 74HC595 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. The storage register has 8 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.
If both clocks are connected together, the shift register state will always be one clock pulse ahead of the storage
register.
