74AHC594
8-BIT SHIFT REGISTER WITH 8-BIT OUTPUT REGISTER
Description
The 74AHC594 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 (SHCP). When
asserted low the shift regisister reset function (SHR) sets all shift
register values to zero and is independent of all clocks. Also when
asserted low the storage register reset function (STR) 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 (STCP). The
storage resister includes output Q7S which is used for cascading
information between devices. As the information moves into the
storage register, it is asserted on the push-pull outputs Q0-Q7.
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.
