74HC597D,653 Datasheet PDF - NXP

●The 74HC597D is a 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 VCC.

● Shift register has direct overriding load and clear

● 8-bit Parallel storage register inputs

● CMOS Input level

● Complies with JEDEC standard No. 7A
