The MC74VHC595 is an advanced high speed 8–bit shift register with an
output storage register fabricated with silicon gate CMOS technology.
It achieves high speed operation similar to equivalent Bipolar Schottky
TTL while maintaining CMOS low power dissipation.
The MC74VHC595 contains an 8–bit static shift register which feeds an
8–bit storage register.
Shift operation is accomplished on the positive going transition of the Shift
Clock input (SCK). The output register is loaded with the contents of the shift
register on the positive going transition of the Register Clock input (RCK).
Since the RCK and SCK signals are independent, parallel outputs can be
held stable during the shift operation. And, since the parallel outputs are
3–state, the VHC595 can be directly connected to an 8–bit bus. This register
can be used in serial–to–parallel conversion, data receivers, etc.
The internal circuit is composed of three stages, including a buffer output
which provides high noise immunity and stable output. The inputs tolerate
voltages up to 7V, allowing the interface of 5V systems to 3V systems.
