74AHC595 Datasheet | Diodes Incorporated

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 (OEሻ asserted low the 3-state outputs Q0-Q7 bee 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.
