MC74VHC595DR2G

The MC74VHC595DR2G from ON Semiconductor is an advanced, high-speed 8-bit shift register with an output storage register, fabricated using silicon gate CMOS technology. It achieves high-speed operation while maintaining low power dissipation.

This shift register contains an 8-bit static shift register that feeds an 8-bit storage register. Shift operations occur on the positive-going transition of the Shift Clock input (SCK), and the output register loads the shift register's contents on the positive-going transition of the Register Clock input (RCK). The independent clock signals allow parallel outputs to remain stable during shifting. With 3-state parallel outputs, the VHC595 can be directly connected to an 8-bit bus, making it suitable for serial-to-parallel conversion and data receiver applications.

Key electrical characteristics include an operating voltage range of 2V to 5.5V and an operating temperature range of -55°C to 125°C. It boasts a maximum frequency of 185 MHz at 5V and low power dissipation with a quiescent current of 4 µA at 25°C. The device offers high noise immunity and power-down protection on its inputs.

The MC74VHC595DR2G is supplied in a 16-SOIC surface mount package. Its pin and function compatibility with other standard logic families simplify integration into existing designs.
