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.

74HC597; 74HCT597 8-bit shift register with input flip-flops Rev. 5 — 26 October 2021 Product data sheet 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 VCC. 2. Features and benefits • Wide supply voltage range from 2.0 V to 6.
