74HC594 - 8-BIT SHIFT REGISTER

General Description

The 74HC594 is a 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).

74HC594 8-BIT SHIFT REGISTER WITH 8-BIT OUTPUT REGISTER Description The 74HC594 is a 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.
