74AHCT594
8-BIT SHIFT REGISTER WITH 8-BIT OUTPUT REGISTER
Description
The 74AHCT594 is an advanced high speed CMOS device that is designed to be pin compatable with 74LS low power Schottky types.
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 register 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).
