74AHC595S16-13 编带
Description
The 74AHC595 is an advanced high speed CMOS device.
An eight bit shift register accepts data from the serial input DS on each positive transition of the shift register clock STCP. When asserted low the reset function MR sets all shift register values to zero and is independent of all clocks.
Data from the input serial shift register is placed in the output register with a rising pulse on the storages resister clock SHCP. With the output enable OEሻasserted low the 3-state outputs Q0-Q7 become active and present.
All registers capture data on rising edge and change output on the falling edge. If both clocks are connected together, the input shift register is always one clock cycle ahead of the output register.
