Overview
The 74HC597D, produced by Nexperia USA Inc., is an 8-bit shift register with input flip-flops. This integrated circuit combines an 8-bit storage register with a parallel-in, serial-out 8-bit shift register. Both the storage register and the shift register are equipped with positive edge-triggered clocks. The shift register also features direct load (from storage) and clear inputs, making it versatile for various digital logic applications. The component is part of the 74HC family, known for its CMOS low power dissipation and high noise immunity.
