8-BIT SHIFT REGISTER WITH 8-BIT OUTPUT REGISTER
Description
The 74HC595 is an high speed CMOS device.
An eight bit shift register accpets data from the serial input (DS) on
each positive transition of the shift register clock (SHCP). When
asserted low the reset function () sets all shift register values to
zero and is indepent 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). With the
output enable ( asserted low the 3-state outputs Q0-Q7 become
active and present th
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.
