1. General description
The 74HC597; 74HCT597 is an 8-bit shift register with input flip-flops. It consists of an
8-bit storage register feeding a parallel-in, serial-out 8-bit shift register. Both the storage
register and the shift register have positive edge-triggered clocks. The shift register also
has direct load (from storage) and clear inputs. Inputs include clamp diodes that enable
the use of current limiting resistors to interface inputs to voltages in excess of V
CC
.
