MC74VHC574 D

MC74VHC574
Octal D-Type Flip-Flop
with 3-State Output
The MC74VHC574 is an advanced high speed CMOS octal
flip−flip with 3−state output fabricated with silicon gate CMOS
technology. It achieves high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining CMOS low power
dissipation.
This 8−bit D−type flip−flop is controlled by a clock input and an
output enable input. When the output enable input is high, the eight
outputs are in a high impedance state.
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.
* Absolute maximum continuous ratings are those values beyond which damage to the device
may occur. Exposure to these conditions or conditions beyond those indicated may
adversely affect device reliability. Functional operation under absolute−maximum−rated
conditions is not implied.

1. Parameter guaranteed by design. tOSLH = |tPLHm − tPLHn|, tOSHL = |tPHLm − tPHLn|.
2. 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 / 8 (per flip−flop). CPD is used to determine the
no−load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
