The MC74VHC595DR2 is an 8-bit shift register with an output storage register, designed using silicon gate CMOS technology. It operates at high speeds, achieving a maximum frequency of 185 MHz at a supply voltage of 5V, while maintaining low power dissipation with a maximum supply current of 4 OºA at 25¬8C. The device features independent shift and register clock inputs, allowing for stable parallel outputs during shifting operations. It supports 3-state outputs, making it suitable for direct connection to an 8-bit bus. The input voltage tolerance extends up to 7V, facilitating compatibility between 5V and 3V systems. The MC74VHC595DR2 also offers high noise immunity, with a noise margin of 28% of VCC, and includes power-down protection on inputs. It is available in a TSSOP-16 package, with options for both standard and Pb-free versions.
