ON MC74VHC595 8-bit shift register with output storage register Datasheet

MC74VHC595
8-Bit Shift Register with
Output Storage Register
(3-State)
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 7 V, allowing the interface of 5 V systems
to 3 V systems.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND v (Vin or Vout) v VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or V CC ).
Unused outputs must be left open.

1. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC. CPD is used to determine the no−load dynamic
power consumption; PD = CPD VCC2 fin + ICC VCC.
